Stands for my young one. It can be used only on people younger than you, even if its only by 4 days. It is a secret term of endearment, for when you would rather use a real term of endearment like babe but don't want to be obvious.

It makes girls smile when you say it to them, especially when you text them, "Goodnight.... myo"

It does sound slightly condescending in a way but it definitely isn't.
Girl: Whatever
Guy:Fine then...myo
Girl: NO! I'm not yours!
Guy: YES! You are!
Girl: okay fine...

the best girl in the world. She is very pretty, smart, but also athletic as well. She is shy at first but once you get to know her, she will talk a lot so she is the best girl you can ever find so you should get with her. She hides things from her friends until she knows she can fully trust her.
Boy 1: Wow I really want someone to talk to right now
Boy 2: Then you should talk to Myo.

Someone who is sexy, hot, and seductive. Myo min is usually a short-tempered guy, but he is an alpha male with a big dick. Myo min will always have your back and will break your back too;), he is a short guy with a big belly which he likes to rub, he always rubs his dick and likes to grab his dick when playing sport. Girls like to throw themselves at a Myo min, but he dodges it with the single "fuck off". So if you know a Myo min consider yourself lucky and cherish that friendship.
Girl 1: "OMG, that guy is so hot"
Girl 2: "I know right he must be a Myo min"
Girl 3: "Let's go ask him for a foursome"
