An adjective used to describe a girl who is very masculine-looking. She may be so unfortunate that it is common for her to be mistaken for a post-op tranny.
It is even more hilarious/suitable when applied to 'girls' named Hailey.
Girl 1: Yuck do you see that blonde girl? She's completely maley.
Girl 2: That shit is rough! Her heavy, cleft chin sure doesn't help.
Girl 1: She looks like your ex-boyfriend in a bad wig.
Girl 2: She probably has a bigger penis.
