Ronda Rousey just shared some very interesting advice she got from her mom -- "Winning is a bitch. But revenge is a motherf*****."
Ronda was speaking at the Women in Action female empowerment event in Chicago earlier Friday -- when she talked about advice she got from her athlete mom about bouncing back after a loss.
The crowd went wild for Rousey -- who was pretty pumped up!
Does this mean she wants another crack at Holly Holm?
She also said, "I want to win my belt back."
BTW, Ronda was sporting a diamond ring on her finger ... but sources close to the fighter tell us it's NOT an engagement ring, just a piece of jewelry she selected for the event.
