Yeah, dancing is fun. I don't know how to dance in any specific style or with proper technique or anything, it's not something I've practiced, I just feel the music and enjoy it, and also try to look as strange and funky as possible while doing it. I don't take it seriously and just try to have fun.
Hardcore dancing and moshing or whatever is fun too at metal concerts. Although I don't really mosh, I just bounce off people and twist around like some sort of psuedo-break dancing jelly amoeba.
