Acronym for My Life Is Average, the nerdier and more entertaining version of Fuck My Life.
Today, I got a new phone and someone called saying my son was say profanities in class and making rude gestures towards the teacher, they gave me the phone to talk to "James" I told him to keep up the good work. I don't have a son. MLIA.
