Skullfapping 

Skullfapping is the better version of skullfucking. It is when you insert your penis into their throat and then masturbate selfishly and as quickly and rough as possible. Skullfapping is best done in a 69 position and is most enjoyable if you have a huge penis. It is standard procedure to fart immediately after orgasm and then pull out and go on with your day with zero emotional attatchment to the act.

"My girlfriend is amazing, she lets me skullfap any time I feel the slightest whim."
"She is hot, would love to have that as my skullfapping toy."

Skullcapping

A sexual action, in which a part of a female's skull is removed, exposing the brain to open air. Then, a male places his genitals on the brain in a style often refered to as "teabagging". The action is highly discouraged as it usually results in death of the female.

Some old man was seen skullcapping Lindsey.

Skulltopping

A superior form of masturbation done by making a light fist over the tip of your penis and squeezing while moving up. It stimulates far more than traditional masturbating and simulates oral. The name derives from the general shape of the hand while it stimulates the penis.

Dude I was skulltopping last night and I blew the fattest load of all time.

I was doing fine in NNN until I figured out how to skulltop.
