A draw string bag that is often used by athletes. it is one of the few types of bags that a guy may use for non-academic material and not be considered gay. it is by no means to be confused with a murse.

A bag held together by string that is typically worn on the backs of athletes for the holding of non-academic material such as cleats, frisbees and lipstick. It can sometimes and understandably be confused with a murse. The owner of the sackpack can be mistaken for a gay man when in reality, he just plays a bunch of sports.
Person 1: Did you see that guy with the sackpack? I bet he plays a lot of sports.
Person 2: Yeah, I bet he's the team rump ranger.
Person 1: Word.
Person 2: Yeah, I bet he's the team rump ranger.
Person 1: Word.
