“dude!! you sh-t in my toilet” -> “where else did you want me to go?” -> “not in the top part you f-ck!!”
while at a respected friends house retire to their restroom, stealthily remove the lid from the back tank of their toilet and steady your cheeks directly above it. begin defecating while trying to keep as quiet as possible. when finished, wipe all remaining fecal spatter from your -n-s and hide the used toilet paper in the cabinet under said friends bathroom sink. when the toilet is flushed by the next user the bowl will be rinsed with your feces. a firm stool will cause repeated minor fecal rinsing, while viscous, soupy stool will flush out all at once filling the toilet thus causing repeat flushing until clean water is present.
the upper decker was rejoiced by all who were present.
