Going bat-shit crazy over a period of time.
Guy 1;
It has finally come to the point where Charlie Sheen, after being cramped up in a cabin, goes after his wife with an ax, breaking down the door with "Heress Johnny!"

Guy 2; I love that movie! It's called The Sheening, right?

Sheen is a very unique person just as her name. She shines just like the meaning of her name. Her smile lights up the whole room. Shes caring and beautiful. Once you are friend with her you feel like your life is complete. Many people has crush on her. She's so sensitive and thoughtful. Everyone needs a sheen in his/her life to shine bright. If you ever met a sheen...be with her forever. Because sheen always understand the situation that others not. Sheen is all in one package.

Sheen is an intimately compassionate person. She is orderly, loving, caring, hardworking and most of all, family-oriented. A Sheen is never to be underestimated. She may be timid and seemingly introvert type of a person, but she shines with the people whom she trusts the most.

Don't anger a Sheen though for they retaliate quite strongly. And they may be quite strict and moody. A Sheen is quite senstive so do not do anything that annoys or hurts her.
A Sheen is someone whom you would enjoy company with. She is loyal, faithful and loving. Anything a man could ask for.
