Gamer uniform 

The default clothes to wear when you have no intention of leaving the house because you'll be spending the rest of the day playing online games. Typically, the gamer uniform consists of: underpants; t-shirt; you're unwashed; unshaved; a cup of coffee nearby; snack food.

Sorry, I can't answer the door because I'm only wearing my gamer uniform.
