YOU SAID:
you are ugly as a hippo and fatchet as a rat
INTO JAPANESE
あなたはカバのように醜く、ネズミのように肥えています
BACK INTO ENGLISH
You are ugly like a hippopotamus and fat like a rat
INTO JAPANESE
あなたはカバのように醜く、ネズミのように太っている
BACK INTO ENGLISH
You are ugly like a hippopotamus and fat like a rat
That didn't even make that much sense in English.
