Spermino 

A cocktail glass full of cum that girls typically drink at the end of blow bang or bukake porn.

Hey girl if you really want me to go through the labor of making you a mojito first you gotta show me ID, and then you've gotta make all these dudes bust in a glass and finish the entire spermino.
