Splashback Enema 

When a dense drop jets a puff of water upwards fast enough to enter the sphincter before it closes from the release.
This requires very specific conditions to occur, and consequently is a rare but possible event

Well boys, it finally happened. I just received a splashback enema. As if that wasn't bad enough I had toilet water overflow from the invasion site dripping down my cheeks.
