When you go take a shit, and the poo drops out from your bum and lands hard in the toilet bowl, sending a splash of water onto your bum, cleaning your bum so you don't have to wipe it with toilet paper.
Oh, WATER SHIT! The water that other people's shit have been in is now on my bum! Now I need to get a towel to... oh SHIT! Now where can I get a towel?
When your fucking toilet clogs and you can't unclog it so therefore causing you to have to scoop shit water out of the fucking toilet making for a very unpleasant evening in your household.
something that is offensive to any of the senses by reason of its extreme ugliness or by being totally devoid of what the utterer considers to be redeeming value.
