Fictitious gangsta term used only by homies on the West Side of Brownsville who are not aware if Harlem residents actually use the term or not. Refers to when a bullet is shot at the top of the head, grazing the victim's scalp and leaving him/her bald.
"Ya'll better not mess wit Juan; I hear he gave Martin a Harlem Haircut after he messed wit his sista."
