What is Dirty Teacup?
1.
The act of forming a very cup-like depression with one's own ball-sack, then filling said scrotal-saucer with a cheap alcoholic fluid of your choosing. Execution involves recruiting the filthiest tramp-whore in your immediate proximity to retrieve the beverage without enlisting the help of her hands.
Dude, remember that tramp in the pink skirt... fuckin dirty teacupped her!
