A "Rog" is someone who doesn't like brews. "Rog" is defined as "a single individual committing an act of Nultonry at a certain time or in a certain place." This can be explained through such behavior which includes hatred for: the taste of brews, the drinking of brews, the loving of brews, being intoxicated, etc..
Sometimes you can witness a "team rog," Though rarely observed in nature...it is defined as, "two or more people engaging in an act of Nultonry at a certain time or in a certain place."
Reference the facebook group: "I LOVE BREWS!"
"Hey, you need to stop being a Rog and finish your brew!"

"How is that Smirnoff Ice tasting tonight Rog?"

"Sorry guys, I have to Rog out tonight and hang out with my girlfriend, drink water, and study."

"'Who's driving tonight?' 'Oh, Rog is."
