A person who dresses in a foul manner and appears to not have showered in days, whose hair is nappy and is in need of a desperate brush and shampoo. Appears to have had a late rough night at a fraternity, which is easy to tell by the frat feet they have. This person lives closely near the Monongahela river (the dirty mon river). Also apart of the commonly used phase "team mon kid".
Worst walk of shame ever I look like a mon kid.
