Mustardmouth 

Mustardmouth is a descriptive word used to poke fun at a person with yellow teeth. The term was coined by a viewer in a TwitchTV chat room, in late October of 2018, during a live broadcast of the “Bubba the Love Sponge” radio show. The host of the show (Bubba) was ribbing a co-host (tuddle) about his dirty yellow teeth and referred to tuddles smile as the “yellow bridge”, when the viewer typed back a paraphrased version of the cutdown “Mustardmouth”. The moniker stuck and now tuddle is forever known as “Mustardmouth”
