Just wondering, for gaybros over 30, do you use ''non-conventional" pronouns?

I am 31 y.o., used to live with some early 20 y.o. and they had friends with all crazy pronouns (no pronouns, all pronouns, etc)

Im just wondering if this is a new trend between the younger generations, or if there are older folks that use custom pronouns too.

For the record, im not trying to be offensive.
