There are all sorts of depraved ways to get a guy's attention. Grab his ass. Hell, grab his cock. I have one friend who liked to "oopsie" spill her drink on guys she wanted to bang. It doesn't really matter how you meet -- it's what you do with his meat afterwards that'll have him crying for more.
For instance, my friend who would "accidentally" spill her drink on a guy started to realize that some people were either too drunk/high/insecure to even turn around and say "hey, you spilled a drink on me!" So she started to get more aggressive. She decided that she was going to start throwing drinks on guys, in what she'd explain would be a huge misunderstanding. Right before she sucked the life out of them.
Once, she made the mistake of throwing a drink on a hot off-duty cop who was not the least bit amused or fooled by her fake story of a misunderstanding. He was about to throw some cuffs on her when she offered to give him the best hummer of his life if he just forgot about the whole thing.
Well, that certainly got his attention.
He had her arrested for bribing a police officer. The charges were eventually dismissed, but she still swears that her method for picking up guys is foolproof. She just asks if they're a cop now before offering any sexual favors.
