When old white guys have little hair and they let one side grow out longer than the other side and comb it over on top of their head.

When a guy is balding majorly in the middle of his head and has long hair on the sides, he combs it over the top of his head and creates the (hysterical) illusion that he has more hair than he really does.

when a woman has an abnormally large fore-head (a.k.a. 5-head) and the man jizz's on it, then flips her hair over. thus causing it to get stuck and cover the previous "bald spot"

Man. If i was old and had a really big beer belly. glasses and spelled like cabbage. i would totally sport a combover. Combovers are awesome.

A combover is when a guy trys to hid his hair loss by taking one portion of his hair and combing it over the patch of lost hair.

A hair style in which the remaining hair upon a bald man's head is "combed over" the bald head giving the appearance of a full head of hair and thus more confidence.

What you do with your hair (usually male) when the majority of your hair on top has gone through baldness but grown long at the sides - you make the most of what is left and 'comb it over' the top.
(Looks okay except on windy days when the comb-over tends to flap about like a flag in the wind!)
