The sound a person makes when they are having an orgasam or taking a dump!
Keirsten : Ahhhh! Ahhhh! Ahhhh!
Craig : Ahhhh! Ahhhh! Ahhhh!
Chad : Ahhhh! Ahhhh! Ahhh! (pause) Ahhhh! Ahhhh! Ahhhh!
Keirsten : Chad did you just fuck me and take a shit in my bed!
Craig : Wait was that in my ass!
The fuckboy laugh, or douche laugh used to sound overly cool. Usually, a pick up line or the like is said and they laugh in this manner, whilst rubbing their chin, licking their lips, or biting their lips, though not limited to only these.
"Wyd Amanda?"
"Just drinking water."
"Would you like to drink something else tonight, ahahaa" *licks lips and runs hand through hair*
