multi layer cake
When walking into a stall and noticing someone has left behind a log in which he or she is proud of. By pinching your more impressive log apon the previous pile you are showing you are more superior. Be sure to not flush so others can marvel over the work of art.
Upon entering the restroom i see my boss leaving one of the stalls. I walk right into that stall and notice he left a feble turd behind. Totally unimpressed I gave him a one upper and left a healthy multi layer cake in the bowl thus proving I am the man.
