The act of folding one's penis downward to allow the shaft to show from an open zipper. This is a socially acceptable act, similar to females showing cleavage. But like the nipple, the tip should never show, referred to as a tip slip
That guy R. Lager over there is showing so much shaft i can't get any attention with my six pack abs and Lambo. If i was packing i would surley show shaft!
