rat's tail 

A haircut where the majority of the hair is cut short, with one long, thin "tail" of hair hanging at the back of the neck, and is often bleached blonde. Characteristic of both bogans and muzzas. Similar to the mullet, but with much less hair left long, and steadily replacing it in popularity.

"Look at the rat's tail on that bogan kid."
