A guy who makes passes at a girl who is already involved with another guy. Frequently using terms like "Weren't you in my Biology class?" - or "Weren't you in Mrs. Jones' Third Grade?". The name comes from the frequent donning of a Sheepskin jacket during the 'pass' phase. Many bold sheepskins will make passes at chicks who are with their boyfriends. Main habitat are local malls.
