Cum Button 

Noun

Pronounced /ko͝om,kəm ˈbətn

Another word for the prostate. The prostate can be massaged for sexual stimulation and can cause longer and harder orgasms. The button part comes from its circular shape and the fact that it can be "pressed" like a button. Often can be pressed to make a person cum/orgasm when they're sexually aroused enough already.

Jenny: I was with this guy last night and he just wouldn't cum; it was getting me angry.
Tiffany: So what'd you do?
Jenny: I pressed his cum button. You should've seen his face when I stuck it up his ass!

belly-button cum 

belly-button cum is the pool of semen that collects in a guy's belly-button after he jacks off his morning wood and paints the wall -- the last of his cumshot dribbles out of his dick and flows into his belly-button.

Oh fuck -- I took care of my morning wood, but I got cum everywhere! -- on the wall behind me, in my hair, on my face, in my mouth, on my neck, tits, stomach, and even had a pool of belly-button cum.
