I don't know if that's the correct grammar lol. Since according to goggles transmit, it translates to the dative/instrumental case (я с тупым) and has a community verified tag on it, but тупым is the plural version while тупой is the feminine singular version of it.
i have, indeed, come to yell
hi yeah yall messed up cases there so it should be "Я с тупым" if its masculine. i think its pretty epic you figured it out without my help doe!
I used wiktionary and a refresher on the cases lmao but I was like, wait a minute is it dative or instrumental...and then i saw, yeah instrumental is used with "с" but is it masculine or feminine..............
