An inflammatory disease
of the colon
. Symptoms are usually painful and involve swelling of the colon and rectal bleeding.
Also is a word that is often mistakenly heard in a line from The Beatles' classic hit "Lucy In The Sky With Diamonds."
When I heard "Lucy In The Sky With Diamonds," I wasn't sure if they were saying "The girl with kaleidoscope eyes" or "The girl with colitis goes by."
