When someone thinks they are working out when they do various workouts during intermissions between Call of Duty games.
COD player: Whoa that was a good game, okay i gotta go take out the trash....

Other Player: Your pathetic everyone here knows your doing sit-ups you lazy sack of cum!

COD player: Sorry it's my Modern Warfare workout.
