Is grinding on the line to bar sexy or pervy?

My go-to move at a crowded club is to line up at the bar behind a hot girl and plant my package between her cheeks. By the time she gets to the bartender, we've been up close and personal for a while, so I lean in and offer to buy her a drink. Four times out of five, we conversate. Best case scenario, I get her number. (If she's kept moving her hips to the music the whole time with my ding-dong wedged in her crack, the odds go up!)

Worst case, she says no to the drink, so I'm like, well, it was fun while it lasted. Occasionally, I'll get a glare and "Would you PLEASE back up!" and I oblige as quick as possible.

So, ladies, if that happened to you at the bar, how would you react. Assuming the guy is attractive, would you find it sexy or pervy?
