A high pitched fart.
Oh my god, did you hear that squealer??!
Like an air biscuit, but hangs around a long time and may be revisited many times.
biscuit? that was a fucking BUFFET!
when you fart so hard your arsehole immediately snaps shut straight after.
god that was an arse cruncher
When someone is shot in the skull.
He needs a painkiller.
