The shortened form of illegitimate.

It is the antonym of legit, a slang term that is the shortened form of "legitimate". However, because the word is often replaced for words like cool, awesome, and dope, the sentences it is used in often don't make sense. Therefore, the word legit in some cases may be, in itself, illegit.
Me: Hey man, those shoes are legit.

Pat: Yes, I know that they exist. Your use of legit fails, and is quite illegit.
