Almost like regular mayonaise, but there's a catch. Payonaise is actually the product you end up with after you've used your vagina as a butter knife to spread mayonaise on your sandwich. Take the V from vagina and the ayonaise from mayonaise and what do you get? Vayonaise. You could also use this as a slang term for woman juice.
Taste like vayonaise!
