Something that suffers from salt and vinegar (chips) Syndrom is universally considered awful and wrong at first contact. But the more you consume it the more you are going to love it.
e.g.:
person 1: When I first started drinking beer, I really hated the taste of it but I've come to like it now.
person 2: I feel the same about techno music. Guess these two really suffer from salt and vinegar syndrom.
