According to Wikipedia, "daddy" is a slang term in gay culture meaning an (typically) older man sexually involved in a relationship or wanting sex with a younger male.
There are currently, however, no references whatsoever on the Wikipedia page.
What is the first documented usage of this term in this context?
For context, I am puzzling over the following lines from Finnegans Wake.
What a quhare soort of a mahan.
It is evident the michindaddy.
If I follow "quhare" to queer, I am wondering if this queer-kuvar-cook mahan-bear-man is merely a michen-underhand- michers-pilfering-poaching-father, or if I am missing something deeper in "michindaddy". I am asking myself if I am seeing a father or a "daddy", "daddy" being rare in Finnegans Wake, as opposed to say "pa"?
