Foom is the sound that's made when your head explodes, like if someone's using too many sexual innuendos in a conversation on MSN.

Foom is the sound fire makes. It's used in the Lenore comic by Roman Dirge.
"O.K., so you like don't remember I was here before and I was frolicking about with a bunny on my head and... and you said 'Let's dance' and I said 'O.K.' and the next thing I knew you're all FOOM with the fire and the evil and the kill'n..."
