@volkris I actually dont but i recognize myself as the exception. Adoping cultural expressions like slang, dialect, accents, fashion styles, or other expressions is something I am strongly averse to. I find it a failing of humans in the genrral sense and not something to adopt.
For example i am from philly and people ofte remark that i lack a philly accent. My accent is generic and as close to having no accent as one can reasonably get.
But to your point, i did figure at first it was an adaptation to the expression of the group they are in. But one thing pointed out is that people who express themselves in this way often begin at a youbg age before joining the gay community or even knowing they were gay.
