A cup which holds cum, primarily after sex.

This was mainly brought into the world by Shane Dawson off one of his"Emo Bop" video where he was pictured with some 'girls' (which was his dressed up). One picked up a cup and went; "Oh is that a beer?" and while she was drinking it, he went; "Oh no no! That's my sex cup!" She spat out the fluids, which was meant to be cum.
"Hey, a milkshake!" "No man, don't drink that. That's my sex cup!"

"Oh no no! That's my sex cup!" "What's a sex cup?"
