Mestie
The term used by females for their male bestie. Best male friend. He is your confidant, your wing man, your partner in crime, your shoulder to cry on and there for you through thick and thin. It's only platonic, but he means the world to you and you never know what shenanigans your futures hold.
I love my Mestie. He's the best guy I ever met.

Girl, have you met Fred? He's the best guy ever. My Mestie. 💗
