Someone addicted to Urban Dictionary

Guy 1: What the hell is an iFinger?

Guy 2: I don't know, look it up on Urban Dictionary
Guy 3: No need guys, it's when you purposely keep clean when you eat something messy so you could operate your touchscreen smartphone/tablet/GPS without making the screen look like your plate.
Guy 1: Since when did you become an Urban Addictionary?
