Literally, "Fuck Y'all MuthaFuckers And Suck My Dick".

Comes straight from the film, "Fear of a Black Hat" (1994), written and directed by Rusty Cundieff.

When pissed off and frustrated with friends (or just for fun dramatic effect)- especially when online, sign off a message/email/blog entry with "FYMFASMD!"
