someone who is definitely a punk but sweet like a muffin.
You're normally so sweet, quit being such a punkmuffin.

Get the punkmuffin mug.
Someone trying to be cool but is instead being an absolute idiot, while also simultaneously thinking they are over-important while in reality being completely harmless.
Look at that punkmuffin bragging about everything and trying to get attention.
