No one says "hazelnut spread", they say Nutella.
No one says "resealable sandwich bags", they say ziploc bags.
TIL what ziploc bags are. Just called "sandwich bags" here. Cling film isn't "sarran wrap" here either. :)
Even then, it may not be. There are plenty of places where Coke has become the generic name for pop, and doesn't necessarily refer to the brand.
Everyone says resealable bags. I've never even heard the word ziploc. In New Zealand.
Perhaps no one in New Zealand, but New Zealand has the population of a small US state.
Because a spoonful of palm oil and sugar with hazelnut flavoring is tasty?
Just went into the kitchen to check
For one thing, Nutella is chocolate flavored. No one would ever even consider calling it "hazelnut spread".
(Compare the consistency of nutella to the consistency of peanut butter.)
Why would your definition be more valid than the manufacturers?
