We kinda speak a mix of American and British English here tbh. British due to our country's history but American too because of the cultural impact of American media.
I hate you damn Americans for making me drop the h from yogurt. I've changed my default dictionary to UK so many times but this bitch ass Microsoft/Windows ho doesn't care.
More specifically, crisps are "potato chips" and fries are "hot chips" (even though they come from potatoes too), but in general most people just refer to both as "chips".
