YOU SAID:
I am the best bestest best I will ever be
INTO JAPANESE
私は今までにない最高のベストです
BACK INTO ENGLISH
I am the best best ever
INTO JAPANESE
私は今まで最高の一番です
BACK INTO ENGLISH
I am the best ever
INTO JAPANESE
私はいつも最高です
BACK INTO ENGLISH
I am always the best
INTO JAPANESE
私はいつも最高です
BACK INTO ENGLISH
I am always the best
That didn't even make that much sense in English.
