Mostly used when you need to go somewhere, but can't hold your shit, in which case you might take a quick shit right then and there.
Often used in conjunction with the word 'dawg'.
Dawg 2 : Dude, I'm not gonna wait for you to finish your brownie. It always takes ages.
Dawg 1 : Dawg, I said I'll make it a quick shit. What do you say? You can even time it and see if I can break the record.
Dawg 2 : Aight dawg, it's on! But make it quick (shit).
* 3:30:08 minutes later *
Dawg 1 : Dawg, I be stinking like crap.
Dawg 2 : At least you got a record of 3:30:08.
Dawg 1 : Aight dawg, let's roll!
