cup and run
According to Bethan Thomas, cup and run is a common series of actions which entails cupping one's vagina following male ejaculation, and running to the lavatory to prevent leakage of semen over bedding, floor and any other surfaces.
"I'm about to blow bitch, get ready to cup and run!"
Cup-n-Run
After a hot night of sex, the woman cups her hand over her fuck hole while she runs to the bathroom making sure the baby-batter doesn't spill onto the floor. Once in the bathroom she dumps the baby-batter into the toilet.
