It is when a female has unprotected sex with multiple men in a short period of time. there is so many different men's seamen in her it is like all the ingredients in a salad. This can be proven on national television on various trash talk shows when multiple men are tested for paternity.
I saw La-Queef on the Maury show and she had the 8th man tested for paternity. That ho had a cum salad up in her.
