Pac-sturbating
Screwing around with Pac-Man or Ms. Pac-Man while you're doing your business.
I played Pac-Man while I was taking a dump. I was like, 'I'm not done until I eat all the ghosts.'
I got a flatulance while playing Ms. Pac-Man. I was like, 'That ghost just died from my farts.'
I beat the level, and my meat went up. It was a double win.
