acronym for "missing in action". Though the term has military origins, it is also used to simply imply that a person hasn't been seen in some period of time.

Mia is a bitch who is the modern day Regina gorge. If you have a friend named Mia then watch your back.

A very small girl who acts very innocent and sweet, but is really two faced. She will stab you in the back when you least expect it. Perhaps (and most likely) when you are closest to her. Ver overdramatic and acts like she can take anyone on at anytime but is realistically very weak. Mias are (generally) very toxic.
Person 1: Wow! Mia's being really nice to me! We're really becoming close!
Person 2,3,4,&5 share an uneasy glance
Person 1: What is it?
Person 2: She screwed me over... Really bad.
Person 3: Same!
Person 4: Yeah...
Person 5: Likewise- and we were best friends!
Persons 2,3,&4: EXACTLY!

The worlds biggest loser. She thinks she’s cool, but in reality, she makes weird scientific jokes that no one understands and is just a freak. No one actually likes her. If you ask her how much a whale weighs, she could tell you in a second. Make sure that if you see a Mia, never interact with her... or you could become a Mia.

Mia is a wonderful girl, her eyes are stunning in the sun light. And her smile is just contagious. She has a one-of-a-kind personality. She is very funny and a bit crazy at times, but you will love her. She has a tendency to be bad at maintaining relationships, because her trust with guys/girls is terrible. But when she loves someone she will give her all to that person, no matter what the outcome is. She is the person that you look for in a crowded room, and let’s not forget on how great of a kisser she is. She tends to be very sarcastic, not to the point where she’s rude. But she is a very sweet person as well. Mia can have bad self esteem issues, so she rarely accepts complements when they are given to her. If you ever have a mia, be very thankful. You will soon regret it if you let her slip through your fingers...
Im glad to have a mia
