No. All of the advice given is this thread is STUPID.
Any GENIUS would know that the proper way to swing dance with a woman is by having yourself grab her by one arm, and have a friend grab the other. Than you both pull on her in opposite directions with ALL YOUR MIGHT. When she starts screaming, you know its because she's having a diddily-fun time!
Sway back and forth you say summer? I think your being rather...

HOT HEADED.
Jesus christ. I really need to turn my internet off past 12:00 AM. Um.... just grab that girl and swing her around... yeah. It's not like you are going on Dancing with the Stars or anything. All you have to do is find a way to entertain the damsel, so start with the swing dancing, than move on to something else that turns her into a giggly googly-eyed freak that will be like:
"TEEHEEHEE! OH MY GAWD AVENGEDSEVENFOLD2012! You are like, SOOOOOOOOOO funny! "
Seriously. It's all about entertaining, but doing so in a way that makes you look good, not like a complete dumb ass. I am probably doing the latter right now... but I'm Vidicus, so it's ok.
