[Tea dance], often abreviated as just "tea", is a term for "happy hour" used among men and women in the gay community. Not necessarily just one hour.
The term can also be qualified by [Kight]" and "low" to qualify the time of day it occurs. Low tea typically takes place earlier in the evening. [High tea] is later. And in some larger gay resorts, such as Fire Island, there is even mid-tea which takes place between the two.
