A momo or momosexual is a male that falls somewhere between a metrosexual and a homosexual. This is usually a metrosexual male that is yet to come out of the closet. Unlike a conventional metrosexual who cares about his appearance and hygiene, he does actually have homosexual tendencies (which he may or may not know about).
"Dude, wearing that pink sweater and baby blue wife beater at the Portsea Pub is really pushing your luck. The bogans aint going to like it. You are such a momosexual!"
A clean-cut mormon who is actually gay but will never be able to come out. Especially if he is on a mission.
Although he insisted he was a soft-spoken, devout member of the church, his friends knew he was a momosexual and felt badly that he would never be able to be himself.
