Goddess Erosia
bow before me owo
I would imagine her position in Equestria hadn't given her very many opportunities for advanced education.
To be completely fair though I'm not sure if this line in the show actually counts as a true grammatical error or if you're just interpreting it wrong. The line is "I could care less about the dress, I won't partake in any cake". It's not too incorrect to stretch the meaning of the song of "lol I don't care I'm just evil" to this line, but imo when I first heard it I imagined she was just saying she's vain and still cares about the dress but she knows it's not important because it doesn't mean anything, and after reflecting on that she won't bother to put up the show for much longer. She's an impostor, and there can be many parallels between her character and traditional "lol I'm a witch I will steal your beauty and become beautiful myself cuz I'm really into vanity like that" trope
