Used to "shotgun" not doing something. Said shortly, and usually quickly, after someone asks for a task to be completed. The last person to say "Shotgun not" must then complete the task.
fathead: I got just got an oz, lets go for a session!
azz: Fuck yeah!
pedro: Got a billy?
fathead: Nah, we need to get one aye,
pedro: shotgun not
