MPG 

Mutual Pain Gain. Sort of like S&M, MPG is when the person giving the pain wants the person recieving it to enjoy it, so that both people gain from the receiver's pain.

Dude1: Are you into S&M?
Dude2: Sort of, but I like MPG, more.

MPG 

adj. Shorthand for "My Pillow Guy." Loosely defined as describing someone who is a little off. Generally connotes someone who is spouting insane nonsense. When used with the intensifier "total" refers to someone who is angry and crazy to the point of being dangerous (synonym "postal")

You need to steer clear of Bruce when he is like this. He stayed up late last night watching conspiracy videos and this morning he is completely MPG. One more night like that and he will be totally MPG.
