Ghost Cup

a term used(in beer pong)to label a cup that has water or beer beneath it. When a ghost cup is hit it slides and moves around the table as if a ghost were moving the cup.

"Hey! Clean up those ghost cups!"
"Make sure the table is dry we dont want any ghost cups."

Ghost Cup

A beer pong related term where the middle row of the rack has been removed. All that is left is the back 3 and the front cup. The removed/invisible center row creates difficult perception.

I can never hit that dreaded Ghost Cup!!
