Muma mouth

A term used to describe a person with very visible gums over their incisors and canines when they open their mouth. The term was popularized because of Overwatch League’s player Muma, who plays for the Houston Outlaws, and his large gums.

“Bro, did you see the new student in class today? She got wicked muma mouth!”

“I was giving a presentation at work and I kept getting distracted because the person sitting in the front had muma mouth.”
