It's not nice of them to tease you, so if they keep doing it and you get tired to ignoring them, just tell them calmly that you think they're being mean.

I do understand your not wanting to dance, but if you say no, some people will become very insistent. You could even play the air guitar on the dance floor. Enjoy and have fun. You know for sure when you go to the wedding they will be trying to get you to dance all night and youll not wanna be in the spot light and youll feel like a party pooper. I say have a few drinks and relax and if they try to get you to dance go to the bathroom or to the bar for a drink, walk around and talk to people.. Keep busy or just offer to take photos for people You dont need an excuse...just say "no". No one is twisting your arm and you dont have to unless you have a few drinks under your belt and decide to do it. I dont dance and was required to dance at my sons wedding. One awkward
