This would work better if the line was simply something like
"Hey you look hot tonight. Wanna f*ck?" if you want to be less brash then, "Hey you look hot tonight, wanna get out of here?".
If you're confident about it and you go to a high energy bar/nightclub, festival, or Mardi Gras type environment, and don't really care about rejection, sure you'll probably get laid a couple of times.
