posiden's kiss 

(Noun) When the gravitational force of falling feces into a toilet causes a splash that touches the butthole of the person defecating. This is often super uncomfortable for the victim, although it has not yet been linked with any cases of PTSD. Simple precautions to avoid this displeasure include placing a couple preliminary pieces of toilet paper into the bowl prior to egestion.

On while on the toilet, John felt posiden's kiss and vomitted ever so slightly in his mouth.
