(n.) A statement whose converse is its own explanation.
A: Girls aren't interested in me, so I don't see why I should care about hygiene.
B: That's an exigology.
Exigology is neither a word nor slang. It was made up in the Saturday Morning Breakfast Cereal webcomic of Dec. 14, 2011.
There are no examples, since exigology is not a word.
