Oh man did you see big dirty last night??
He's big.....he's dirty....your girlfriend hates him...he's big dirty Blake!
To best encourage a successful Big Dirty one must recite "Big Dirty" multiple times. How loud one can say "Big Dirty" is up to the speakers discretion. This repetition can also be used to invite others to perform a successful Big Dirty.
Reciting "Big Dirty" can also be used to set an uncomfortable tone in any crowded restroom, public or private.
Stall 2: Inhabitant leaves the restroom due to uncomfortable atmosphere.
