Rectal Rain

The act of putting ones anus up to a strainer and then shooting diarrhea through the strainer to give the effect of rain. This maneuver is recommended to do upon the face of a prisoner, a sleeping child, or any other unexpected organism.

I made rectal rain all over my cat.

When all the diarrhea has poured out of your anus (or whatever orifice it escapes), the butthole makes a promise to never flood your pants again.

I hope a rectal rainbow rescues me from the aftermath of that gas station burrito.
