A renaissance man/woman of horrible things. A Buttbag is a person who is part attention whore, part pretentious hipster, part fake yuppie, part drama queen, part conceited douche and part self-righteous asshole.
Perfect examples are: Kanye West, Tom Brady, Christina Aguilera. A great fictional example is
Sarah Marshall from 'Forgetting
Sarah Marshall'.
Did you see Aunt Jane's daily Facebook posts about how she's in mourning for her dying
father....but according to her he's been dying for
15 years AND she threw in
something about being a great caregiver and how everyone else is a horrible person. Man she's such a Buttbag.
