To shoot someone, most likely a hater of some sort. Usually a gansta, will make this threat. But on occasion a wanksta, will make this threat you can usually tell the two, for example a gansta will be an angry black man screaming and making a big deal about something very small, and a wanksta will be the white guy in baggy pants of some sort and wearing a 5XL shirt trying to look hard but making a fool of himself.
