The soreness one feels in the legs after a long night of drinking. Usually coupled with beer shits.
"I totes have keg leg, bro"

The act of duct-taping an empty beer keg to your left leg and walking around with it. You need something to do with that empty keg. And when people ask why you have a keg strapped to your leg answer with, "Arrrr, they was out of pegs."
