MS Orifice 

Synonym for overpriced and widely hated software program MS Office, offering functions that should of course have been preprogrammed into any OS and free of charge in the first place.
Hopefully soon to become abandonware thanks to open source software OpenOrifice (Open Office).

J-hole (The Jucuntius Orifice) 

A fictional, vestigial Orifice hidden deep in the anal cavity. Seldom cleaned and commonly burdened with excessive waste material, it is generally understood to be an undesirable hole.

The Jucuntius orifice is located several inches deep into the anal cavity and is 2 inches deep x 1 inch wide.

Oh! I'm an A-hole, well you're a J-hole!

The J-hole (The Jucuntius Orifice) is worse than the anus.
