To vomit as a result of excessive drinking, motion sickness, or a flu. Basically, to crap from the mouth.
Pull over, I think I'm going to drop a mouth deuce.
I should not have had those last few drinks. When I got home, I mouth deuced all over my living room.
I'm not going to be in today, I've been dropping mouth deuces all night.

pinch a loaf, take a dump, you know.
It's associated with "going number 2", because number 2 is "the deuce"

Lavinius and Cooch were on their 2005 MLB Midcoast Trip when Cooch needed to drop a deuce at a nearby truckstop.

The most epic shit that anyone has ever shat or ever will shit. A thunderous eruption of excrement unlike any the world has ever known. The kind of shit that puts all other shits to shame with its impossible magnitude and regal malodorous splendor.
Felix: I just took an incredible shit.
John: Yeah, that's great dude.
Felix: You don't understand, Jonathan. I've dropped the Deuce of Ages. It was magnificent.
John: Uh-huh.

Masturbating while pooping. Killing 2 turds and 1 bone. The splooge deuce can be enjoyed by both males and females. It is most enjoyable when you time your orgasm as you pinch a turd off.
My girlfriend and I were making out but because of her menstrual cycle and the diarrhea that accompanies it, we could not make love that night so instead we went into the bathroom together and watched eachother enjoy a splooge deuce.
