bad muffin 

A phrase often used to depict someone or something that is "tough" (and, or) "too cool for school".

Like walking down the road late at night with my sunglasses on like I'm a bad Muffin.

Bitch, I'm the baddest muffin on this webpage.

Bad Miffin

When bae is being a bad lil bitch, but you can't necessarily call her a bitch.

Hey Leah, can you not be so rude?
I'm not listening to you.
Don't be such a bad Miffin.
