DOUCHE

A person, GENERALLY a man, who is shallow & hot...a PLAYER with a SLICK game. He is USUALLY very attractive & well-groomed, but his lack of conscience and self- absorbed behavior renders him completely intolerable to be around.

"I am horny, but MY GOD, He's such a DOUCHE... I just want to punch him in the face."

put a shine on

Pretending to be happy when you're really not.
To make the best of a bad situation.

Some things just suck, but you put a shine on and get on with it.
