YOU SAID:
i am the best person in the world and you are not cool
INTO JAPANESE
私は世界で最高の人であり、あなたはクールではありません
BACK INTO ENGLISH
I'm the best person in the world and you're not cool
INTO JAPANESE
私は世界で最高の人だし、あなたはクールではない
BACK INTO ENGLISH
I'm the best person in the world and you're not cool
That didn't even make that much sense in English.
