Nactivewear
The clothes you wear to look like you're going to the gym, but you're really just going to the nearest McDonald's because you're too tired to walk.
I wore my activewear to the gym. I saw the McDonald's across the street and walked there instead.
I bought activewear because I thought it was a fancy version of pajamas. I was wrong. It's a fancy version of a food coma.
I wore my activewear to the gym. I did 10 push-ups. Then I got a McDouble.
