Deuce

1. The preferred nomenclature for a two (2) in poker.
2. Common slang term for excrement.

Usage for Definition 1

It's generally regarded as nerdy to call a 2 a "two." So when you have the hand 22 in Texas Hold 'Em, you should refer to it as "a pair of deuces."

Usage for Definition.2

From an actual conversation in an elevator at Foxwoods involving two PPPs and one random stranger:

"Wow I really gotta drop a deuce."

"Too much information."

"Sorry, I tried to keep that on the down-low."
