when a man and woman are performing missionary, and right before climax, the man punches the woman in the stomach as hard as he can, causing her to ball up (like an armadillo) and then ejaculates in side the woman in fetal position.
hey bro! I heard you Armadillo punched Amy last night! how was it?
oh it was great, i punched her so hard it was almost as if I actually came in an armadillo!
