A responsible traveler won't set foot in another country without knowing how to viciously insult the people in their native language. Odds are, you won't even make it out of the airport before a situation arises that requires obscenities. But "obscenity" is an ever-moving target. It's an amalgamation of cultural taboos, the impact of current events and your mom. Accordingly, every country has developed a uniquely beautiful set of curses and insults that set it apart. While some insults are broadly accessible, like your mom, others will require a little background for the new student. Thus, we offer this helpful guide to the best and most vulgar (and very real) insults from around the world: Advertisement

9 "Suck butter from my ass" (Chupe mantequilla de mi culo) Who Said That? The Spanish. Dear God Why?

How does a culture wind up with "suck the butter from my ass" as an insult? It's starts with "Me cago en la leche," meaning "I shit in the milk." It's a common statement that's essentially a variant of "Damnit!" We're unsure how milk + poop = a jaunty, multipurpose expletive, but here we are. Other helpful Spanish phrases:

When dookie is used for even the most pedestrian exclamations, more heated applications escalate the filth factor pretty rapidly: Continue Reading Below Advertisement "I shit on your dead" (Me cago en tus muertos) "I shit on God" (Me cago en Dios) "I shit in/on your whore mother" (Me cago en tu puta madre) Note that's "in" or "on," we guess depending on how she likes it. And the list goes on. These folks just love shit. Basically you can hold your own in any argument in Spain if you're creative enough with where you deposit your waste matter. If you're a man who is sharp enough to destroy someone with this virtualized shit-flinging, pride may reward you with a "Brazo de santo," which literally translates to "arm of a saint" which means a full erection.

If you thought Spanish had an unusual fixation with fecal matter allow the Arabs to put it in perspective with their penis-based potshots. Describing someone as a "fatah" (foreskin) alone is considered a grave insult and that's only the tip of the proverbial/metaphorical ... iceberg. Other helpful Arabic phrases:

"May you be struck by a dick" (Air il'e yoshmotak) "My dick in your conscience" (Airy fe dameerak) "My dick in your mother's rib cage" (Eyreh be afass seder emmak) That's not to say they're just smut peddlers insult-wise. Some of the most disrespectful things you can say are 100 percent penis-free like "Surmayye a'raasac" (A shoe is on your head). The foot is considered the most filthy part of the body, courtesy of their deserts not having any shortages on dirt. To direct your foot at someone verbally or physically means you aren't hiding your contempt, as vividly demonstrated by the thousands of Nike treads upside Saddam's bronze dome (right). Continue Reading Below Advertisement That explanation was a lot easier to track back than "Yela'an sabe'a jad lak" (Damn your seventh grandfather), which is the deepest scope of damnation demonstrated by any culture thus far.
