Mo Bro

What does mo bro mean?

A movember participant

A mo bro is a term used to label a male participant of Movember, which is the mustache-growing campaign to raise awareness for men's health issues during the month of November. The term comes from combining the abbreviation of "mustache" or "moustache" and bro.

A mo bro must have some level of facial hair growth. The amount of hair differs between each mo bro since their starting points may be different and hairiness differs. However, mo bros with little hair growth should not be criticized because they're at least trying.


I love seeing all the mo bros that come out of hibernating this month
