One who engages in such activities as larping, Magic the Gathering, or other such activities that push you further away from losing your virginity. Some common signs of a slarm are greased hair (usually hasn't been washed for days), wears clothing 3 sizes too big that was passed down from his older, older brother who was also slarm, shoes tied so tight his feet are screaming for air. And the #1 sign of a slarm is.....a pull backpack.
