Backwards Hannah
To spray faeces out of the anus in such a radial fashion that the entire circumference of the bowl is covered in a fine film of nard. The only logical explanation is that the owner of said faeces mounted the toilet backwards in order to achiever such coverage. Named after a certain girl from Ormond College who absolutely splattered the porcelain after a night on the turps.
There was so many skidmarks on the toilet he must have done a backwards Hannah!
