Really salty peanuts.

Reasons:

'PEA' nuts rhymes with 'SEA'nuts.

Salt is commonly found it the SEA!

It's just logic.
Man 1: Hey, wanna peanut?

Get the Seanuts mug.
Derived from 'cunt' where deliberate misspelling to 'cnut' is used to bypass online smut filters. A more polite way of calling someone a 'cunt'
It had to be said, Ben is a seanut.
