A person who drinks from a keg for hours, trying to finish it so it doesn't go to waste, and ends up ridiculously drunk from the effort.
"Yea dude, I snagged the keg from Dana's and tried to finish it yesterday. Yea, I drank from 2pm-till 2am. I think I'm still drunk."

"You're such a kegster. Idiot lol."
