John was pissed because he had a half full/empty cup of beer.

Full Beer Flip Cup
A version of flip cup played by a room full of bros and preferably without shirts. Cups must be filled to the brim. This may or may not induce intense vomiting.
After a game of full beer flip cup, half the room chanted "FULL BEER...FLIP CUP" while the other shirtless bros puked in the corner.
