oh yeah.
so brits call american chips, crisps, and in britain, chips are what we americans call fries.
which is probably how we have, "chisps"
so potapto chisps would be crisps and chips, with potato, following suite.
if you're british this information is confusing because it's either wrong, or it's right and confusing in the way that chips and chips are 2 different things.
