Nubbinating 

When you get carried away with nail biting and you gnaw down so far that it makes your fingers hurt. Only leaving a little nub for fingernail.

Kelley you need to stop nubbinating or you won't be hungry for lunch.

Nudisting 

Getting naked, then rubbing your butt on objects, getting butt and genital germs over them.

I want to sit down here, but some guy was nudisting at this seat, so I don't think sitting down here would be sanitary.
