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.
