An insufferable jerk you used to
know - such as an
arrogant jock in high school - who later is humiliated by baldness and must resort to a comb over or comb up, or alternatively
just wears a hat all the time.
Friend: Did you see that
dickhead Colt at the 10-year reunion?
Me: No, I heard he was too embarrassed to come because he's fat and
bald now.
Friend: Wow, he really received his combuppance.
