That said, it is still considered slang. (No es un modismo. Es un argot.)

Aquí te copio la explicación en inglés (viene a decir que una persona gay respondería así, en el sentido de "¿cómo está/-s?")

A popular phrase coined by radio DJ and tv personality, Wendy Williams. How You Doin?! is not only a greeting of the show, but when something or someone is very gay.
Jordan *Very feminine and flamboyant*: Hey miss honey, what's goin on sweetness?!
Kalisha: How you doin?!?!

That word is very popular in a movie.
How you doing.
I have understood when I have heard some movie with that slang, the I interpret myself as Como te va.

I don't know if am in the right.
I'll stand with the perspective of a answer of some native around.

Les agradezco a todos por la información.
