Guesterbate 

The act of masturbating while staying as a guest in someone else's home. Particularly entertaining if it is in the home of someone you do not like.

Harper: "Hey Chuck, I'm going home tomorrow, so you can have the room to yourself."
Chuck: "Thanks man, but I don't need it."
Harper: "You sure? I've been around all week."
Chuck: "I'm good bro, I guesterbated in JJ's room last night while he was asleep."
Harper: "Awww man that's dirty, wish I woulda thought to do that."

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....

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.

Excess amounts of firearms and firepower, whether it is in real life or in a video games, that makes the user want to "nut" in excitement.
