When people wear Under Armour, or other athletic gear, everywhere they go, at all times, for no reason, even though they are out of shape or are not working out. Commonly seen in grocery stores or malls.

Another implication is that they have just come from the gym and have not yet cleaned themselves.

Often seen on children of rich parents.
G-Man: Are you on your way to the gym?
D-Man: No, I just bought the new Black Ops game. I'll be inside all day.
G-Man: Well that explains your Over Armour
