a boy with a cunt, aka a female-to-male (FtM) transgender/transsexual who hasn't had bottom surgery (and in this case who looks like a boy instead of a man, like some FtMs do).
I really dig cuntboys. There's just something really hot about a boy with a cunt.

Fictional gender and an oxymoron]: flat chested] male who has a pussy instead of penis, and is able bear children.

This term was made up by furries. It was originally used sarcastically on for special snowflake] characters who were so different that they needed their own gender. Sometimes used seriously by those who aren't aware of its origin.

Cuntboy is also occasionally used as an insult for transgendered individuals.
My fursona] is a cuntboy. He is both male and female, but too special to be a herm]. Don't question it.

when a chick has so small of boobs that when she takes her shirt off she looks like a boy
Is that a chick or a guy?" Bob asks Bill. Bill replies, "I don't know. Go ask it." Bill walks up to this particular flat chested person "Excuse me, are you male or female?" The person answered irritably, "A female of course! What did you think?" Bob replies, "Oh, so sorry. I just thought you had no boobs at all. You look like a cuntboy, but come to think of it you're just a cunt.
