Top definition
A person (often white, often male) who reeks of privilege but is clueless about it, and makes arrogant, sweeping, offensively stereotyped statements about huge groups of people about whom he knows nothing in an attempt to sound like "deep thinker" or some kind of intellectual. Craves media attention and thinks that all black people are male and all feminists are rich and white. From n.: Alex Knepper, douchebag who famously caused a stir at American University by claiming that "date rape is an incoherent concept."
This knepper in my class didn't know anything about the civil rights movement but he wouldn't shut up about it until he pissed everybody in the group off and we ended up wasting the whole study session.
