This phrase is used to refer to hair that disheveled beyond belief -- for instance, after a particularly crazy fuck session. It was inspired by the beehive fuck mess hair of Amy Winehouse. It take "bed head" to a whole new level. It can also refer to your general appearance after sexual activity when euphoria eclipses vanity.
Damn, my hair is a total fuck mess; I look like Amy Winehouse.
This was a typo ("Fpre" instead of "Fire") posted in the title of an Internet article in Monterey County after the Soledad Canyon Fire. It took on new meaning as aimless travelers began to replace fire with fpre in all their conversations.
Wow, Pete Yorn is hot -- I want to make love with him down by the FPRE!
