Well, ballroom dancers do, though I doubt that lard ass will be doing that.

Word ballroom hasn’t been used literally in like forever They’re just huge rooms for events, dancing included

I'm literally in a ballroom every week. That seems more recent than forever. Some people even compete in them. Some people just do it for fun. But they are called ballrooms. There's a whole world out there...

I’m actually a ballroom dancer I think you misunderstood my point All the big event rooms in hotels are called ballrooms regardless of useage

Ok, I did misunderstand. So actual ballrooms do exist but some rooms called ballrooms aren't really ballrooms. I'd agree with that. And it's doubtful tRump will be doing any dancing in his 'ballroom'. Certainly none that I'd want to see. Glad to hear you're a dancer. It's a lot of fun.
