cock in the henhouse
The only male in an all-female environment. Getting a male teacher is a big deal when you go to an all-girls school! Finally, a cock in the henhouse! My grandpa always complains that he's a cock in the henhouse living here with my grandma, my mom, and my twin sister. Yeah, I'm the only guy in that class, but being the cock in the henhouse is not exciting when none of the girls are into you.
