A man who walks around with deer rage. One who possesses excessive hormones. "The frusterated One" a.k.a. "Test" a.k.a. "John Holmes". This guy hasn't gotten any for a while, and is on the prowl looking to end his dry spell and cure his mad bone.

Rick: "How could I miss him? He was raging!!! Those eyes..."

Melissa: "What's a Mad Bone?"
