11 Down: Barry Bonds is one. (7 letters)

Source: This is a clue I saw in a crossword puzzle once. OK, it might have been 6 letters, but 7 letters seemed more appropriate...

Explanation: Barry Bonds (a baseball player and alleged steroid user) is a total jerk. "Total jerk" doesn't have seven letters, though. "Scumbag" does, but I wasn't thinking of that word in this particular case.
