You really want to think twice before pulling down your pants to give the gluteal equivalent of flipping someone the bird.

Philadelphia - What began with two teenagers harassing a man rummaging through a trash bin escalated when the man bared his buttocks at the teens and ended with the teens killing him, police said.

Personally I think Christopher McEneaney, 16, and Andre Mark, 18 of Philadelphia, PA overreacted on that one, whacking Martin Malone, 47 with a shovel and stabbing him (mostly in the ass!) until he died.

I guess the teens will have plenty of time to think about what they did in the slammer, where I’m sure they will become somebody’s ass-buddy rather quickly!
