An extremly tall mellow guy who gets extremly close up to you and while talking, looms, or sways their balance and teeters over you dangerously in a way that freaks out your personal space.
It is unintentional and done by the extremly loaded or high. Not to be used for a creepy person, but a friend that just doesn't know how to control thier balance and height. Often a tall scraggly hippy, or one who has spent many days living in a tent.

Aaron: Curtis! You Loomer! Just quit loomin' and just go to bed! Sleep it off man..."
