An enormous and/or monstrous poopie that is taken in the morning after a long days digestion.

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 1: "Big Dirty, Big Dirty, Big Dirty"

Stall 2: Inhabitant leaves the restroom due to uncomfortable atmosphere.

A type of belligerent persona, often found passed out fully clothed with open food around him, with the t.v on full blast. Notoriously known to be "forever alone" this specimen will continuously attempt to prove himself despite making a mockery of himself hours ago.
Wow! What a big dirty...

Oh man did you see big dirty last night??

He's big.....he's dirty....your girlfriend hates him...he's big dirty Blake!
