1.
A rapper and multi-instrumentalist from Minneapolis, Minnesota. He is one of 9 members of Doomtree, a group of MC's and DJ's from the twin cities. He's also a part of the Rhymesayers record label, which is also home to others such as Atmosphere, MF Doom, and Brother Ali. P.O.S is very talented, although not very well-known. He has three albums at the time of writing, Ipecac Neat, Audition, and Never Better. His real name is Stefon Alexander. P.O.S doesn't definitively stand for anything, but it's been know to mean Pissed Off Stef, Product of Society, Promise of Skill, Promise of Stress, and even Piece of Shit (a joke).
A guy: Hey I heard you went to Taste of Minnesota 2010 on July 2nd?

Another guy: Yeah! I saw Minus the Bear, The Walkmen, P.O.S, and Atmosphere!

A guy: That must have been great!
