Y!A 

The best website on the internet. Just don't say anything about sex, drugs, swear words, masturbation, whores, killing, abuse, violence, Alabama Hot Pockets, or anything else FUN. If you do, beware... you will get reported and will get a violation. And not the good kind.

Person 1) Someone on Y!A said I should break up with you.
Person 2) Maybe I should break your face ho!
