Can't be destroyed. Will last forever.

Inviolate

Free from violation, injury, desecration, or outrage.

At this rate of depredation, I doubt there is a single inviolate spot on Earth.

Invisable Girl 

After sex with your partner you go about your daily routine in their house acting like you can not see or hear them.

Dude, I got to do the Invisable girl to this woman last night.
Did you tell her that you were doing it?
Of course not.

invismable

(v) The act of beings so enthralled with Visma, that you lose all awareness of your surroundings and you perceive it that no one is able to see you or your actions.

By the way they were carrying on in the night club, you would have thought they were invismable.
