OOP Anti-Objects

Has anybody heard of this anti-object concept in context to the OOP paradigm?

Wikipedia once had an article but like most good things it sometimes gets deleted.

I believe this gets mentioned here:

A comment to that article couldn't have said it better. Anti objects are just objects, and the whole pacman thing was just adding another object, the "scent" being trailed by the ghosts.
