Biff

In short, a dick fart. The male version of a queef. Although this is physically imposable, it is a hilarious concept. Used as a derogatory term.

If you don't think this word is funny, your a biff.

The main character in the book, Lamb The Gospel According to Biff, Christ's Childhood Pal. He invented sarcasm.

"La-la-la. Hey Roman guy, too bad about your getting stabbed. La-la-la. It's probably not a message from God or nothing. La-la-la. Telling you that maybe you should have gone home, la, la, la. Instead of oppressing the chosen people who God hisownself has said that he likes better than you. Fa, la, la, la." -Biff, when distracting a Roman gaurd so Jesus could bring a man back from the dead when they were young.
