bb gun: A type of gun that shoots bbs and/or pellets. It is not a firearm but it can be as fast as 1000 FPS. bb guns are commonly used for competition and target shooting. Lots of teenagers think they look cool by shooting it because some look like real guns. They use it to shoot windows and other peoples property just to be ass holes. If you get one threat it like a real gun. Be safe.
My brother and i both got bb guns to target shoot.
