Uh, no I literally don't give a fuck - I just think it's funny that you have a problem with a kid saying "oh biscuits"

I'd say a swear is a swear - you know what swear words are, and I didn't decide anything, society did. Personally I don't really care and I swear like a sailor but there's probably been books written about what is and isn't a swear word, how they came to exist and why they exist for all cultures and societies around the world. Maybe there are some exceptions but every language I've learned about has swear words in it.

Language is silly.
