The act of fornicating whilst rolling around in a 3rd party’s vomit.
Adam: “hey Laura. I fancy you quite a bit. I know it’s our first date. Instead of a dick slap in the face how about the Hastie Wastie?”
Laura: “ a Hastie Wastie?”
Adam: “yes laura. Sandra vomited her chunky tomato soup outside on the doorstep. Let’s put my Agnus Monster into your Monica Cherrybrook whilst rolling around in juicy chunky tomato vomit”
Laura: “why yes Adam! Give me that vomit covered schlong”
Wassies are tiny creatures with room temperature IQ. They are usually a mix of platypuses, frogs, ducks, or penguins and the result of radioactive incidents or mysterious apocalyptic events. Their short lifespan extends further if kept in a fridge after which they respawn with the knowledge of their ancestors.
Some people derive amusement from targeting them, while others passionately stand up to their defense but wassies simply cannot be stopped or eradicated.
