Someone who is absolutely repulsive and seemingly inbred. Most likely has webbed feet, and ginger, or some form of strawberry blonde. Sports a pale face, and eyes that resemble oriental orientation. See, disgusting, and as my friend favours, vile.
There is a very good, fine specimen of a munter currently sittng across the table from me, right at this very minute. So much so, I've taken a photo and it's available to see on the images! She's blonde, pale, and chinky looking. Enjoy!
Something/someone who is unattractive/ugly/offensive to the eye. Northern English term. A step up from the word "minger". Perhaps suggesting even more unflattering to the eye.
Can also be used as the verb eg. "She munted for England".
