Stands for Fuck My Life. A popular website (fmylife.com) where people can post about shitty things that happened to them.
While a lot of FML stories are fake nowadays, they can still be plausible and entertaining, unlike the faggots on MLIA who post about how they got chased by some dude dressed in a banana suit at Walmart.
Today, I thought it would be funny to tickle our high school's star wrestler. He responded by punching me in the face. FML.
Stands for My Life is Average. MLIA is a spinoff of FML that was originally created for users to document daily life. However, it has now been infested with homosexual suburban white children who make up fake stories and post them in an attempt to impress and make other people laugh. The demographic includes Harry Potter nerds, Twilight haters, Justin Bieber and Miley Cyrus haters, 5-year-old suburban white girls from Nebraska, etc.
Posters frequently post about how something awesome happened at their school, such as a professor dressing up as a banana and reading fairy tales to the class. Quite obviously, these stories are fake; if they were real, then all MLIA posters probably attend Faggot High School.
MLIA posts are supposed to begin with "Today" and end with "MLIA". However, many posters are so busy fabricating their bullshit stories that they forget to do so. Recently, a trend has developed where posters chronicle an exciting event and end their post with a matter-of-fact statement, such as "Life. Complete." or "I love _____." This statement is meant to be the "punchline" of the pathetic joke that posters are trying to tell.
Real MLIA post:
"Today, I went to Burger King for dinner. Then I went home and watched The Hangover. MLIA."
Note the documentation of events that truly happen in average life.
Fake MLIA post:
"Today, I woke up and decided to dress up as Harry Potter. When I got to school, I discovered that my friends had dressed up as Harry Potter characters as well. Then all of a sudden the entire grade started singing "The Mysterious Ticking Noise" in the hallway. I love my school. MLIA."
Note the documentation of an event that could never happen, except at Faggot High School in Homoville, Nebraska. Also note the homosexuality portrayed by the poster and his matter-of-fact conclusion of "I love my school."
