Gumsturbate 

When one chews gum extraordinarily loud and obnoxiously, causing you to lose your ability to concentrate.

Man, can you gumsturbate elsewhere? Your loud smacking is giving me a headache.

Guesturbate 

Masturbating when a guest in another's house. Carries extra shame but oh so naughty at the same time!

My aunt put me up in her basement for the night as I traveled through town. Couldn't sleep...I tested the bed for creaks, then naturally I guesturbated. I'm pretty sure I pulled it off without detection! yet at b-fast I couldn't help but wonder if she was looking at me funny....

Harper: "You sure? I've been around all week."
