Stands for Stoned Midnight Tagger which originated in the Pacific Northwest but has somehow made it's way into the Midwest. Typically a confused middle to low class teen who feels everyone hates them but have convinced themselves they don't care. They can be spotted easily as they usually listen to shitty music such as ICP and yell profanities at random people passing by, but when confronted they are known to run. See Juggalo.
