|1.||Reverse Combine Harvester|
A Bristolian sexual act whereby the man is upside-down on his shoulders pushing his erect penis forward so that it is pointing towards the ceiling through his legs.
The female sits in a seated position on the man and leans as far forward as possible creating a kind of circular shape (the harvester).
The man after harvesting for some time then proceeds to push a turd from his anus, the perfect consistency is loose and bitty to mimic the spreading of the seed after the harvest.
