Apparently this tribal knowledge has not been passed down.
If someone at school is bullying you, go to any pawn shop (there's one in every town) DO NOT GO TO THE RIFLE WALL, TURN AROUND and go to the OTHER wall, and buy one of these. You can purchase one at any age. There is no background check. They are cheap. There is no waiting period. You can open carry them anywhere. Take it home. Practice. Talk to other dorks that wear the same shirts you do. Start a band. Get loud. Scream about how rotten it is that everyone is against you and no one will sleep with you. Get it all out.
DO NOT KILL ANYONE.
