First coined by Lydia Fraley McCormick in roughly 2005, it is the act of pretending to fire rockets out of your own or a childs ass as if it were a rocket launcher.
"I'm going to make the baby dooker shoot you" by holding the child on its back, gently jerking the leg, bent at the knee, back towards you like cocking a shotgun with the babys butt aimed at the person, and issuing the noise associated with children pretending to fire a gun.
