I had never heard the term “down-low” until today.
Down-low (sexual slang)
From Wikipedia, the free encyclopedia
For other uses, see Down-low (disambiguation).
Down-low is an African American slang term[1] that refers to a subculture of men who usually identify as heterosexual, but who have sex with men; some avoid sharing this information even if they have female sexual partner(s).[2][3][4][5] The term is also used to refer to a related sexual identity.[5][6]
About 4 years ago, I read the term was used in the "black community" to refer to a man who was living a double-life. Now, I can't use the term in the older sense.
