What kind of party is 黑灯舞? I heard that in the past, around the 1980s, people could be executed for this. But what does it consist of? Is there an english/american equivalent or something similar?
黑灯舞 sounds like the direct translation of 'Black Light Dance' a.k.a. 'U V Light Dance.' (dancing in darkness with U V Light on)


But according to this article  黑灯舞 refers to &quot;dancing in a dancing hall under very dim light&quot;
黑灯舞, in this case, should be translated as &quot;(indecently) dance in the darkness&quot; (darkness make it easier for people to have indecent physical contact)
I think many people nowadays would use 黑灯舞 as the modern term for 'Black Light Dance'
