Any female who is more masculine than her boyfriend. Her physique is typically bulkier than that of her significant other. She also has a deeper voice and weighs more. It's speculated that mangirlfriends even have more facial hair than their boyfriends.

On top of all of this, a mangirlfriend is usually ugly as shit. If one didn't know she was a girl, one would swear she was a bear. Once one discovers she's a girl, one immediately assumes she's a lesbian.

But no, she is in fact straight, and usually extra slutty in hopes of proving this. A mangirlfriend's boyfriend is typically either desperate for companionship or is basically on the verge of being a twink. If the latter is the case, the difference in masculinity is extra humorous.
Mortimer: "What the hell? Why is Jacob sitting in his girlfriend's lap? Shouldn't it be the other way around?"
Jimi: "MANGIRLFRIEND!"

Kaylee: "Fuck Austin and his fucking mangirlfriend!"
Ajay: "Hey watch out, he might have her beat you up."
