BAFAN is a mnemonic for "Bust A Fat Ass Nut". BAFAN means to expel a great deal of semen all over a girl during an intense climax.
example: "Dan pulled out and BAFAN'd all over her ass!"

example: "man, this day is stressin' me out. I gotta go home and BAFAN."

example: "man, I've been tryin to get with this cock tease for months. I just want to BAFAN all over her!"
