A style of headbanging in which a metalhead swings his head in a clockwise circle in time to a metal song, causing his hair to fully extend and swing like a pendulum.

Invented by vikings, made popular by Amon Amarth, and exploited by Suicide Silence.

Inexperienced headbangers may find it hard to keep their heads up after a night of windmilling.
Example 1:

Scene kid: So I hear that you windmill too! *begins hardcore dancing*

Metalhead: Fuck your shit. *whips up tornado with hair*

Example 2:

Metalhead 1: That Amon Amarth concert was fucking awesome.

Metalhead 2: Hell yeah, but my neck hurts from windmilling too hard.

Metalhead 1: Pussy.

When you are wearing tighty whitey underwear, and the crotch piece rolls up and becomes twisted so that your penis is hanging on one side and your balls on the other. Similar to a jean jam.
