I'm my own MILF - "MILF" was a username decided on early, standing for "Machiavellian Intelligence/Laissez Faire", which wouldn't fit in the username field. A forum in-joke led to the phrase "I'm my own MILF!" often being used after a lengthy declaration of one's political views, and he adopted that as his name. "MILF" later became popularised as meaning something entirely different.
