Mouse on my face

A friend who is trying to learn English through Duolingo surprised me today by mentioning that "mouse" has a colloquial meaning I never heard before - a black-eye.
I was wondering how common the usage is and why I never heard it  before (I live in the US Midwest region). The examples I've found online mostly mention it in a sports context, such as "a boxer is going to have a mouse there."  Is this the area where it's mostly used?  Or is it more specific to a geographical region?  Have you ever heard/used it?
Thanks!
