A girl with bad fat eats fast food every evening followed by a Ben&Jerry's. This contributes to bad fat which gives her a huge flat ass, hanging boobs, sticking out belly, and in the more severe cases a double chin.

These types of girls are bad catches and should be avoided, unless she is a friend of a hot girl of course...
T: Hey man, check out that girl's ass! I wish i could rip those jeans off and do her all night!

J: Nah man, that's bad fat... You don't want a sumo wrestler doing you all night do you?

T: Uh huh.. Then what's ..good fat hmm?

J: *Shows a picture of girlfriend on phone*

T: Whoah! Shit dude how'd you get a girl like that!? I mean, her body is perfect!

J: I've got my tricks ;)

Get the bad fat mug.
When someone is being the absolute worst (stealing memes, abusing power in Discord, etc.)
Nohl: "Does anyone have anything to say before we banish Jordan for meme stealing?"
Cooper: "Lol yeah Jordan is fat bad"
