Kind of Mohawk worn by a jock. Most commonly a soccer player. Shaved sides, usually not very tall, and wider then normal mohawks, 3-4 inches wide. Maybe an inch long on top, rest of head completely shaven. It is a completely rad hair style.
Soccer player 1: yo man im tired of my stupid hair
soccer player 2: hey! get a jockhawk!
soccer player 1: good idea!
