from a guy who likes to dance, 1 tip would be introducing urself pretty quickly instead of just dancing and leering.... personally, i NEVER, EVER rub up against a girl or touch her. after talking to her, if she wants to dance with me cool...,.if not, i just smile and go my way. treat the girls with respect and they'll give u respect back even if they aren't interested. which often leads to u meeting her friends. the more people u meet, the better chance of meeting someone u like and likes u back.
