undercover yummie bird

A young man, usually from late teens to early adulthood, hiding his homosexual tendencies. An undercover yummie bird must be good looking, give away hints of homosexual behavior but yet deny any accusation of same sex physical attraction.

That man is looking at the guy all the time, I am certain he is an undercover yummie bird waiting to be discovered.
