Haha, listen to nova, get that fivesome going! Tell em you got lots of lovin' to share!

About other groups giving you evils. You could quite easily use that to your advantage. Go back to the group and say something like "Heeeey, are you to continue staring at me on the dancefloor or are you going to come and show me these moves of your eh?" something along those lines. Those 'looks of evil' can be directed at anyone though, so be careful.
