An Alelitist is a person that ONLY drinks craft beer and gets persnickety with others for drinking anything they feel is less than awesome. An Alelitist would rather tell you about a beer, as opposed to share one with you.
"Hey where have you been, you left four hours ago?"
"your brother's house...I asked if I could grab a beer for the road. he said sure...and then proceeded to tell me the malt characteristics of every French beer made from 1842-1934...what a fucking Alelitist that guy is."
