A huge party for a girl at 15 to celebrate growing up. Similar to Latin American Quinceanera or the Sweet 16 party common in the USA.
She decided to have a Fab Fifteen instead of a Sweet Sixteen.

A group of girls that Michael Pesce and David Nierenberg are obsessed with. They wish they could join the Fab because they are the top two guys that are usually always hanging out with these extraordinary group of girls.
\"Yes, it\'s true we did make up the fake Mike Stackpole entry, but only because we adore you guys!\"
