We've all been stuck in a lobby with one of these unlikable goons. Read on to make sure you're not on the list.

With large and diverse following, the Call of Duty series has more than its fair share of insufferable gamers who pollute the online multiplayer experience. We've all come across unsavory sorts while firing our way through Modern Warfare, World At War, and Black Ops, but which are the most loathsome? Check out our list below.

10. The Dead Weight

These players come in all shapes and sizes. Some gamers can't help their poor skills; they simply aren't blessed with twitch reflexes or haven't familiarized themselves with the maps yet. Some slowly drink themselves into a stupor over the course of the night. Others are hopeless parents investigating what this whole video game fad is all about. Whatever the circumstances, no one likes seeing a teammate rack up 2 kills alongside 20 deaths in a team deathmatch round. With dead weight like that, you're better off finding another match than suffering through the unavoidable streak of embarrassing losses.

9. The Kid

The last four Call of Duty games were rated Mature, but that hasn't stopped irresponsible parents from letting their prepubescent brats jump online and ruin the fun for everyone else with their high-pitched voices, incessant lobby singing, and eardrum shattering shrieks. These entitled kids defiantly keep on blabbering despite the chorus of "SHUT UP" that inevitability rains down from every rational human being in the game lobby. Odds are these obnoxious rug rats are the reason Activision added the mute toggle in the first place.

8. The Lone Wolf

A breed of annoying gamer born out of years of deathmatches, the lone wolf only cares about the personal glory of a positive kill/death ratio. That's perfectly fine in TDM, but when you jump into Domination or Search and Destroy it's time to set aside your narcissistic goals and be a team player. Not these stat freaks. Instead of helping out with the objectives, these jerks run to their favorite camping zones, and justify their go-it-alone behavior it by saying their godly kill numbers are helping keep the opposing team away from the objectives in the first place. What's the big deal about a great K/D ratio, anyway? Are you awarded 7,000 vestal virgins when you die? Is it something you can put on your resume to find gainful employment? Here's the bottom line: Nobody cares dude. When even Ice-T is sick of your crap, it's time to take a look in the mirror.

7. The Stoner

The stoner is the easiest annoying player to spot. For many of these mind-numbed gamers, it's not just a hobby, it's a lifestyle. They showcase their support for THC by using pot leaf emblems, picking Gamertags with "420" somewhere in the name, and by telling everyone in the lobby how unbelievably high they are when they arrive in the match. If you can tune out the crappy jam band playing in the background of their mics, you can even hear the faint sound of bong hits in between spawns. The marijuana may take away their pain from repeatedly dying thanks to diminished reflexes, but there is no secondhand smoke to ease the agony of their now-shorthanded teammates.

6. The Mouth Breather

Your team has proven surprisingly communicative, trading intel on enemy positions and informing each other when someone needs backup. Suddenly, the cooperation comes to a screeching halt when an abrasive white noise fills the mic channel. The mouth breather has arrived. No one else can communicate when this subhuman is dominating the coms with his weezing, coughing, and garbled speech. Turn down the freaking microphone, move it away from your fatty lips, or maybe go for a jog. Your poor health is bleeding through our Xbox Live headsets, and it's making everyone uncomfortable.

5. The Blamer

No matter the circumstances, the blamer is mentally incapable of taking responsibility for his or her own death. Like a pathological liar, the blamer is armed to the teeth with an impressively lengthy list of premeditated excuses for their poor performances. The lag kicked in right when they rounded that corner and got lit up. The servers are glitchy. The other player is cheating. Their allergies caused them to sneeze and that's why they abandoned cover and ran right into a crossfire. Sure buddy. Whatever you need to tell yourself to sleep at night.

4. The Teamkiller

Everyone has accidentally downed a teammate who walked into their line of fire, but the ninth circle of hell is expanding to make room for this special form of treacherous pest. Like an arsonist holding a can of lighter fluid and a matchbook, these short-attention span pranksters can't resist watching things go boom – even if it's their teammates in the spawn base. They're not above firing a rocket launcher into a group of comrades, giggling uncontrollably as the downed players groan in frustration and disbelief. Taking out a teammate is also their first solution to a location dispute. If you move into a position they feel entitled to, the teamkiller won't hesitate to put a bullet in your back.

3. The Armchair General

He's never been on a tour of duty in Iraq or held a gun in his life, but watching weekend-long Military Channel marathons has given this insufferable player an encyclopedic knowledge of mundane details he can't wait to shower other players with in Call of Duty. When he's unable to shoot a player across the map with his SMG, he snidely comments that the real MP5 has an effective kill range of 600 yards – the game designers clearly don't know how to balance weapons. When you successfully escape the blast radius of a napalm strike, he casually remarks that you wouldn't have survived in real life because one firebomb has the potential to lay waste to 2,500 square yards. Thanks for the fun facts, Cliff Claven – now can you shut the hell up and let me enjoy the game?

2. The Cheater

This unfortunate breed of d-bag ruins the competitive balance of a match by exploiting glitches the developer hasn't patched yet. Even when the devs squash known exploits, this devious community digs for new ways to gain the upper hand in ill-gotten ways. The worst of this breed may be the boosters – players so obsessed with having a prominent spot on the leaderboards that they go off in a corner with a Milhouse-like minion to start inflating their stats. Is a high prestige and an obviously forged kill/death ratio really that desirable?

1. The Rager

These jag-offs are the primary reason many gamers shun online multiplayer altogether. When the Rager isn't spewing hate speech by calling every downed enemy a "f-g" or "homo," he's blowing out your eardrum with primordial grunts, screams, and other baser expressions of emotion that call to mind the intellectual savvy of a wounded animal. These blowhards randomly select gamers to antagonize, threaten bodily harm on anyone who talks back regardless of the fact they they are often located thousands of miles apart, and inevitably turn on their own teammates when their side falls behind. The only saving grace of these agitators is that they can't handle losing, and often drop out of matches if they end up on the wrong end of a winning streak.
