I'm headed to Vegas next weekend and it's really the only time I go clubbing so I'm kind of new to this. I'm a pretty decent looking guy, confident, wear nice clothes, and I feel like this works to my advantage at clubs. I'm vegas I feel like the dynamic is a bit different - I find myself traversing through the dance floor and girls will brush up against me or come and dance next to me. I guess my question is - if a girl brushes up against you, is the best move to throw your hand out for a dance or to whisper something along the "what's your name" line to start the interaction? This bothered me the last time I went to Vegas because it would totally throw me off and I would feel like I let myself down because I didn't know what to do...

Thanks! Any other dance floor, clubbing tips are much appreciated
