Fellatiation 

A form of initiation in which fellatio is a requirement. (note: this was made to keep those annoying fucking seventh grade whores from getting to the back of the bus when they became ninth graders.)

They must go through fellatiation before they can obtain the coveted back seats on the bus.

Autoerotic fellatiation 

The act of performing oral sex on ones own phallic member to the point of choking and passing out.

John rushed home from yoga class to go blow himself as per usual, his roommate was home early so John hid in linen closet and feverishly began to take himself to his own base. Pounding his pallet with the cold robotic force of an off balanced washing machine caused the sowing machine to fall off the shelf and on top of John in the middle of fucking his own brains out. The autopsy determined it quite easily to be death by autoerotic fellatiation due to post mortem positioning. Balls to brows, John died choking on his dick.

fellatialingus 

The combination of fellatio and cunilingus performed simultaneously. Or simply put, 69.

Last night, my woman and I decided to do a little fellatialingus. I love when she bobs my knob while I eat her kitty.

Fellatitious 

Something, usually an argument, of such poor quality that it eats dick.

Mike - "So how come you don't like 'Thriller' It's arguably one of the best albums of all time"
Bob - "Idk man I just don't"
Mike - "That sounds a little fellatitious to me"

fellatiotone

Fellatiotone is the extreme muscular development that occurs when someone gives a lot of head. In developing fellatiotone the giver often feels muscular tiredness in the cheeks and a stiffening in the jaw. This passes once true fellatiotone is achieved.

Julie: "Gee whiz my jaw is tight and my cheeks are sore!"
Zoe: "Girl, you need to work on your fellatiotone. Once you get to be as good at giving head as me, your fellatiotone will be awesome!"

fellatiatoe 

When you're getting head and the girl rides your big toe.

This girl was giving head to me and stuck my big toe in her pussy. That fellatiatoe got me off real quick.

Cross-fallatiation 

A mutually beneficial deal or contract in which both parties assist the other for a common goal.

I will advertise your restaurant if you let me eat there for free. Commence the cross-fallatiation
