heads up ? screw you !

I was at a ball game and someone yelled "heads up" when a foul ball went into the crowd. WTF is that ? Heads up is going to get someone smashed in the face. I'm calling for a moratorium on the phrase "heads up" and asking that it be replaced with the phrase " duck motherfucker".

Goddamn Im hungover...but not to hungover to remember how bad that McNabb sucks.
