Someone who takes a strong liking to inserting randoms objects up peoples assholes to probe areas of the intestine and colon not yet studied by doctors and air port security guards.
When I asked Kristen what she was going to get her degree in at Auburn, she told me butt probing. When I asked her why she said it was because she liked taking household objects and ramming them into people's assholes.

Get the Butt Probing mug.
1. General name for an object used to manually explore the "butt".

2. Any otherwise innocuous object repurposed to insert for torture of a deserving individual.
Someone should post that Civi’s new Legendary mace would be best used as a butt probe….. on him!
