P90Puss - A lazy person who says they're doing P90X so they can sit on

A lazy person who says they're doing P90X so they can sit on the couch and eat pizza instead of actually working out or hanging out with friends.

I’m doing P90X, so I can’t go to the party. You’re on your own.

I’m too busy doing P90X to help you move. Good luck.

I’m doing P90X, so I’m not coming to work. You’re fired.
