A small goatee which forms itself around ones chin whist brushing the teeth.
The floride and mint extract in the toothpaste results in the goatee being minty.
"I has a mint goatee"

"Mike, you've still got a bit of mint goatee on your face"

"Your Mint goatee turns me on...you want to know why? Coz it reminds me of cum. My cum... all over your chin. Have a nice day :)"
