Salt yes
A phrase said randomly, usually to call and obtain a response from someone else who is close enough to hear it.

Salt yes is also used when asked what it means. As a random and strange response. But, if people hear it, it can actually be kind of funny.
Guy one: “what does “salt yes mean?”
Guy two: “salt yes.”

Guy one *yelling* “SALT YES!”
Guy two *in response* “PEPPER NO!”
