Wotsits is a brand of cheese puffs sold by Walkers. The most common form are cheese flavoured curly shapes. However over the years various other shapes (such as waffle-shaped Wotsits) and flavours (such as prawn cocktail and BBQ beef) have also been sold. The brand name occurs in the singular, "Wotsit", referring to an individual corn puff. Like many such names, it is an allusion to a common word, in this case the slang term "whatsit", to which it is phonetically identical. Wotsits packaging often come with a joke or trivia section on the back.
