#1. Fist fucking- the act of stuffing a fist up a pussy *owch*
#2. Foot fucking- a type of masturbation that women do to their male partners dick.
#3. Final fantasy- a game played by geeks, such as my boyfriend, that I should probably learn to play.
#4. Fan Fiction- a type of writing that uses already made characters from books and movies and such that have sex, also called slash... gay LOTR ones at www.libraryofmoria.com.
#5. Father fucker- a person who likes to fuck their dad/friend's dad.

FF
Stocking fetishist abbreviation for old-fashioned stockings from the 40's and 50's that are knitted flat and sewn together leaving a distinctive back seam. Authentic full fashioned stockings also have a top welt made by doubling the fabric over and sewn with a small hole in the back seam called a "finishing hole".

Look, it matters to you if it matters.
