"--Don't wear a knife, let it be known that you own weapons, or are into the martial arts."
"I was into the martial arts for years, but finally realized that women don't give a rat's a$$, and in fact viewed me as some sort of violence-obsessed loser. "
That's strange. For me and others guys that I've known, girls seem to dig the fact that we are into martial arts. It's not like they get all into it, but they do seem to get excited and be like "oooh show me some stuff!" It also adds to that whole strong protector thing girls look for. That has just been my experience though. To each his own ; )
