Hair tied into a bun that resembles a ball sack. A potential sackhead begins as a perky, well proportioned bun. Through continued exposure to life, that once perky bun becomes a sagging shell of what it used to be.

If a friend is sporting a sackhead, it is your duty to promptly alert them of the saggage upon their head so they can fix it immediately.
