When someone spits saliva or urine into another persons butthole.
Make sure you use the human bidet after you take a dump.

human bidet is that special class of creature that feels the need to prostrate themself behind bosses, managers, social higher ups such that they give an extra ass cleaning, far beyond the normal ass kissing. Human bidets are close relatives but much luckier than human urinals, who constantly get pissed on by everyone.
That idiot got promoted ahead of me. He wouldn't have got this far if he wasn't such a human bidet!
