Mullet

In heraldry a mullet is a star-shaped charge (though it is distinct from a heraldic star). Unless otherwise specified it is drawn with five points. It often found with a hole in the middle, betraying its origin as the representation of a spur-rowel (the rotating bit that jabs the horse).

Mundanely, a mullet is a ghastly haircut, long fore and aft, close cut to the flanks. Only the Normans knew how to look worse with their bowl cut.
