When a guy's dick turns greenish-yellow as a result of infection from anal sex.
Idiot: "This girl was sucking me off and ended up cutting my shaft with her teeth. Proceeded to anal, the next day my entire dick was like a jaundice-y greenish yellow color. Turns out, bacteria from her poo got into the open cut and infected my entire johnson."

Guy: "Dude, you got jaundeuce."

Get the jaundeuce mug.
When you get a cut on your dick somehow, then you fuck a chick in the butt, and the next day your dick is yellow and green with infection.
"Dude why is your dick that color?"
"Jaundeuce bro... jaundeuce."
