fuckabulary 

A person's knowledge of sexual positions, in the same way as VOCABULARY means "a person's knowledge of words".
This word was invented by the webmaster of Sexpositons.com.au
You can test your fuckabulary and get a rating on the website fuckabulary.com
(Sorry editors, I read that you are not supposed to advertise websites here but I thought that in this case it was relevant to know who invented this word and where to find more info on it).

So in the same way as a person's VOCABULARY determines his ability and creativeness in being VOCAL, a person's FUCKABULARY determines their skills and creativity in the numerous ways of fucking, and other ways of having sex.

Fuckabulary 

When one's vocabulary is riddled with swear words.

"Man Jake's always swearing, it's like every other word is a swear word!"
"I know, he has quite the fuckabulary."

fuckcabulary 

A vocabulary revolving around the word fuck.

An MV'er said that she uses the word fuck a lot in connection with other words - fucktart, for example. I suggested that she widen her fuckcabulary with such classics as fuckton, fucknut, fuckmunk, fuckmuppet, and fuckquake.
