B up A 

B Up A. Refers to Modern Warfare (MW2, COD4, World at War). It means to "give up" or "tap out" and back out of the lobby before the game starts. You can tell someone to "Bupa" (sounds like "Boopa") if you want them to leave.

Example 1:"Man, you guys have no skill- you keep using your noob tubes". "Noob tubes? These are pro pipes. B UP A"

Example 2: "I don't noob tube, I bro-pipe!"
