look up any word, like dirty sanchez:
to creep up along side someone, preferably outside of a tent, as they are sleeping, to lift up the tent flap and immediately beat the flogging hell out of the subject, aiming directly for the ribs, and then to proceed to run away in laughter and jubilation.
A slight variation of this is when, as the tent flap is lifted quietly, the subject has a towel or shirt placed over the face in order to sustain the covertness of the puncher.
Ariel, Max and their minions go up alongside Zachary's tent, Ariel lifts up the tent flap, gets the good morning punch, and Max finishes the bashing with six solid punches to the ribs as Zach, quite unlike his friend Yoni, groans in pain.
