a person, when at a show (hardcore, punk, sxe, etc) gets into a mosh pit, or up to the mic, raises their arms, and flails them. this technique usually pisses off alot of people as it usually hurts anyone dumb enough to get close to this guy. high stickers are usually idiots or first time moshers; hopefully the latter, in which case they can be forgiven.
me: oh man, i just got smacked in the face by some stupid high sticker at tonights show
other guy: bummer. noob?
other guy; then hes a tool.
