A disease that causes a 'pen lid like' growth on the anus, this causes faecal matter to come out 'like play-dough hair'.
The infection is generally spread by the act of rubbing anus' together but in some cases can be hereditary.
There is no known treatment for Lidanusitis, but in some cases victims have attempted to simply cut off the growth, this results in three more 'pen lids' growing in it's place.
What's up with that Guys arse?
Oh, he just has Lidanusitis
