Charlie Sheen went crazy insane at the Staples Center Wednesday night, after a security guard told him he could not re-enter the stadium after taking a smoke break -- and it's all caught on video.

A female security guard that was not gonna put up with nothing would not budge when Charlie tried to get back in. Charlie snapped and starts screaming and yelling, "You know what?  F**king blow my balls, alright, you f**king a**hole." Nice right?

Charlie's buddies tried to keep him away from the camera but failed. The "Anger Management" star then explains, "Have common sense and common courtesy gone in society? That was what I was trying to impress upon her."

The Staples has a policy of not letting people in once they walk out. Charlie left the stadium without ever getting back in.  He told TMZ, "Bad juju. Clash of the silly." And then took one last shot by saying, "Go Thunder!"
