Idiot, moron, one who lacks the most basic common sense to make correct decisions,see ass clown.
That fuck whistle doesn't know his ass from a hole in the ground!
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".
