the act of delicately inserting the tail half of a live salmon in a woman's vagina to arouse pleasure while the mouth end of the salmon is positioned to receive the penis of a male. In this sexual innuendo usually the male and female are to reach orgasmic climax once the salmon is deceased.
My pen pal Emma from Iceland invited me over to her home country to go Salmon sloshing. It's a yearly tradition for her family.
First I heard the water run and fill the tub followed by the couple laughing and splashing around together. Later, all I heard was moaning and rhythmic sloshing.
Irresponsibly aggressive and wet female masterbation, usually soaking the shoes and socks to make a sloshing sound when walking: shoelaces must be untied.
