The sound a guy makes as he shooting his load in his girls ass. Usually either a long moan or just simply going "Oh Yeeeaaaahhhhh!!!.....
"I could swear the neighbors heard me when I blew the fuck whistle while fucking my girlfriend last night dude".

Fuck whistle is the sound made between rolls of fat when two fat fucks fuck. It's not quite a fart, not quite a whistle. ...and no, it doesn't smell great.
