Defined by the awesome sport of curling. Curling Bum is the amazing tightness of a chick's butt created by prolonged playing of the awesome sport of curling. The characteristics of a Curling Bum is tight, firm, round and flexible. These characteristics are intensified when worn with Lululemon pants.

While in the stands at the Scotties Tournament of Hearts for the best Ladies Curling team, I have to shift myself in my seat mutiple times when stairing at the awesome site of these Curling Bums.
