Cum in a cup

Used when giving oral sex (blow job) or when having sex with someone to dispose of the ejaculation. Hence the term cumming in a cup

Any container used to hold liquid (such as a glass, mug, or a cup), that could be potentially used to cum in, that has been cummed in, or is frequently cummed in.

A cum-cup is an 8-ounce plastic/paper cup that a group of guys use when they play "cum-in-a-cup" -- a masturbation game similar to "cum-on-a-cookie." All the guys jack off and shoot their loads into the cup. The last dude to have a cumgasm has to drink all the other guys' cumshots.

The dimples on a person's lower back right above the booty and on each side of the spine. Used to catch cum when a man unloads on your back/ass.

It’s seriously the weirdest thing on here
No one does this

Used to reference the anatomically modern female humans' dimples commonly found situated within the lower back region that corresponds to directly above the buttocks.

This word's creation/existence may be attributed to the potential for pooling of ejaculate within the aforementioned dimples upon employment of coitus interruptus birth control methods during acts of sexual intercourse that involve rear-entry position-type sexual positions -- such as doggy style.
