Used in turn of the word "Feces" or any other appropriate slang words

fun monkey (aka front monkey):
To straddle the toilet the opposite way round when pinching out a log in order to leave an unsightly skid-mark down the front side of the toilet basin.
When round at a friend's humble abode, be sure to leave your fun monkey (aka front monkey)mark whilst not forgetting to relay the blame upon someone else, preferably someone's girlfriend.
