ASKfm Social Network Decodes Most Commonly Used Internet Slang ASKfm, a popular question and answer site, dissects the most common terms.

 -- Welcome to Internet Slang 101.

We've come a long way from the days when LOL was the only piece of Internet slang a user really needed to know. ASKfm, a popular question and answer site frequented by teens, released a list of the most commonly used acronyms and slang terms used by its more than 150 million members.

If you understand this list, you may be the GOAT (that's greatest of all time) when it comes to Internet slang. Here's a look at some of the top terms ASKfm recorded on the site -- along with their more proper English translations.

OOTD

That's short for outfit of the day. One way to engage on the site is to share a snap of your OOTD or ask for fashion feedback.

PAP

"OMG (Oh My God), wait until you see my OOTD," Erica said.

"PAP!" Rebecca replied. In other words: Post a picture.

Bad

When you say someone is "bad," it means you think they're great, or "something even more positive like hot," the team at ASKfm explained.

Ship

This is short for relationship.

Savage

Savage is used to describe something hardcore and impressive -- such as pulling off a new BMX trick.

IDEK

When you're at a loss of words, you may exclaim "IDEK." That means "I don't even know."

TBR

When someone is about to share something harsh, they may begin a sentence with TBR. That's "to be rude."
