Bassturbation 

Putting ones scrote on a large bass speaking whilst listening to a remix of any Adele song until you ejaculate.

Last night I bassturbated so hard it measured 9.7 on the richter scale.

Gerald - 'Last night, i had to bury my pet dog Gravel'
The Boss - 'What happened, Gezza?'
Gerald - 'Bassturbation'
The Boss - 'I lost my infant to that, no wait.... i stabbed him in the face, never mind'

I really wanted to go down on her last night, but when I got home she was in the middle of an assturbation session to the new Justin Timberlake video.

bansturbation 

A fusion of “ban” and the term for sexual self pleasure.

This refers to the public abuse of the rights citizens, as things that some people simply disapprove of are made illegal, plus the near-sexual frisson of pleasure gained by those who pass such laws.

Lifestyle engineers want to ban everything we enjoy, they get their kicks from bansturbation.

assturbation 

Masturbation restricted to the ass region. Usually performed by placing dildos, buttplugs, fingers, toothbrushes, or whatever else may be handy into the anal cavity. Lube is optional but highly recommended.

Suzy had never considered assturbation until she overheard Julie talking to Maria about shoving a 9 inch vibrator up her ass while fantasizing about Tom (Suzys dad).
