An idiot, someone who's a jerk or difficult.
Dane Cook is a total totebag
A douche bag of the NPR variety; who is obsessed with "local" foods and "green" anything. This person goes beyond the normal caring person, and is truly annoying. Will most likely have a beard and/or a retro street bike.
Did you see Tom over there?
Who is that?
The totebag, the one with the beard.
