At this week's seminar, Prof. YOSHIMU said to a student that
あんまりテキトーなことばかり言ってると…怒っちゃうよ.
(Your irresponsible comment will make me angry.)
So, this is transformed to TSUNDERE-form such as
あ…あんまりテキトーなことばっかり言ってると…お…怒っちゃうんだからねっ!
(Your irresponsible comment will ... may make me angry.)
in my brain.
I think this means that it is clearer that the Tsunderization of him makes progress than ever.
