What craziness...being a guy..i usually just approach a girl and ask how she is doing, if she is having a fun time, and ask her what her damn name is, and remember it!
Some lines my friends have used:
This one my friend got slapped so hard he flew into a wall,
"Girl, if we were squirrels, would you let me bust a nut in your hole?"<---that's just jacked up.
Guys....listen...you want to talk to a girl, ask her how she is doing, get her name and remember it and if she's drunk, stop trying to get her to come home with you, if she likes you, she will remeber you in the morning, so always exchange numbers just in case.
