The act of straddling a toilet bowl the opposite way, in order to slide your kank down the front end of the porcelain, thus leaving the maximum among of skid per kank behind. Best performed at fizz parties in Osterly where the host has not provided enough entertainment. Often following by childish laughter.
"Mot just did a reverse kank in his own toilet! He'll never get those stains off!"
