Pocket-philosopher 

Someone who tries to be deep, but just comes off as pretentious, or having no life experience.

Guy 1: "People just are horrible, human beings are pathetic creatures and everyone is garbage. Live life as you please, because you only get one."
Guy 2: "Wow, playing pocket-philosopher today are we? What other common sense covered in sugar are you going to give me next?"
