A "shower" a female takes underneath the cum of her partner. Sometimes the female will even smooth shampoo or conditioner- or any other type of nomal shower product and use it in this cock shower to make it seem more legitimate. Usually followed by normal intercourse or a birmingham booty call just for the hell of it.
man: Hey want to go in the matress store and take a chup
woman: sounds good- why dont you give me a chup in the chipotle bathroom also?
man: i could dig that
woman: i hope you drank lots of pinnapple juice...
