On accident
I kind of can’t take people seriously when they say On accident, I don’t know or care if its more or less grammatical, it sounds like a child sputtering in my mind. It should be By accident
or accidentally
Tummy
Any adult has zero business saying this lol
You might not say one seventh (sic presumably quarter is meant) of January, but you’d still be correct in every sense (except, again, mathematically) if you did.
