Even if you flatter me, I'm not fooled that easily—I'm not so stupid as to be taken in by being called sensei.
A set phrase combining 先生 (sensei, a title of respect), と言われる (to be called), ほどの (to the extent that), 馬鹿 (fool), and でなし (is not). The literal meaning is 'I am not such a fool that being called sensei would affect me.' The exact origin is uncertain, but it reflects a common cultural trope of deflecting praise.
