Caffrey Cup 

While playing 10 cup beer pong, the Caffrey Cup is the cup in the exact middle of the rack. It came about in late 2007 when a young beer pong talent by the name of Sean Caffrey had a tendancy to hit the middle cup every first shot.

Some also say the sinking of the Caffrey cup on the first shot is the premonition of a guarenteed win, but that is debatable

--Dude, you hit the Caffrey cup every fuckin time.
--That's why they named it after me man.
