tankplating

/tank-pla-ting/ noun

A vile prank, originally made famous by the French, where person secretly defecates into the reservoir of a toilet. Generally, much care must be taken to stealthily manipulate the reservoir cover in order to avoid alerting the owner of the toilet or any nearby potential witnesses. Once the tankplating process has been completed, the feces usually disintegrates completely within 48 hours leaving a foul, semi-permanent odor emanating from the reservoir.

We took a video of Timmy tankplating the women's bathroom at the local gas station. I can't wait to get this up on Youtube...
