A group of around 40-60 people on 4chan's /trash/ board who like furry cartoon girls but are anti-furries. Basically, they are closet furries who do not want to reveal themselves and feel shameful about themselves.
Have you seen those "hmofa" people on 4chan?
Yes I have, someone should tell them only furries date furries.
HMOFA (human male on female anthro) is a genre of romantic and/or pornographic fiction involving a male human and a female anthropomorphic/furry character. In most examples of works in this genre, the human character has minimal defining traits in both appearance and personality, as to make it easier for the audience to project onto him. It is primarily popular on 4chan and other spaces outside the mainstream.
I played an interesting HMOFA game about a guy and a wolf girl falling in love during the apocalypse.
Boys who enjoy yaoi (a genre in Japan that contains sexual and/or romantic relations between two men); literally translates to "rotten boy"; corresponding female : fujoshi
