The act of grabbing your own sack/balls after achieving a "user sack" in Madden. You must yell "User Sack" while grabbing your sack simultaneously. An excellent form of gloating
After Bill controlled Brian Orakpo to sack Tony Romo, he grabbed his sack and yelled "User Sack" at the top of his lungs, much to the disgust of his friend Bobby.
