A word describing the dimples on the lower back of a girl/guy...When said person pulls out his penis and "nuts" on the back of the other person.
Two people having sex then the male pulling out his penis and ejaculating on the lower back, NUT CUP, of other person.

Get the Nut Cupmug. During sexual intercourse; the male locates a red solo cup shoves it up his significant others ass then jacks off into the shit stained cup. He finds pleasure in this action by dumping the shitty cum filled cup into the others vagina, or cockhole if it is gay sex.
