mangirlfriend 

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."

man-girlfriend 

A male friend who is a surrogate replacement of a girlfriend or spouse in a heterosexual way. MGs are in near constant communication and may talk more than an actual girlfriend or spouse. Similar to a wingman but with more responsibility, a man-girlfriend will do anything that is typically done by a girlfriend (other than sex). Seth and Evan, in the cult classic Superbad, were man-girlfriends.

“My man-girlfriend hasn’t called me today and I’m starting to get a little worried.”

“Dude, have you talked to Brady lately? What the hell is his problem? His man-girlfriend is out of town and he’s going into withdrawal.”
