Talking with Nettie, I we come up with a couple more possible Cowboy Up parodies. They would all have the chaps, but different upper bodies and sayings...
bodysaying
A mohawk and flipping the birdPunk up
Dreds and a bong (Nettie's excellent idea)Smoke up
Bald head and a leather cross strapLeather up
Upper body of a copDoughnut up
A joint and a booze bottleFucked up


One could make a whole line of these...
