She didn't put the lid down to flush and now she has poomonia.
(noun) The extremely distant yet unmistakeable feeling - almost a sixth sense - that despite having completed the initial and ostensibly main phase of your poo session, there is another wave of dumping still to come.

Sorry I'm late, but I had a major poomonition. Thank God I took proper heed, because it was a dump that I'll never forget. I feel great!
