"Ok" can also be an annoying reply:

Prestley: Think about it! Roland: Ok. Prestley: Stop saying that, I want a straight answer, now! Roland: Ok. Prestley: Stop saying "Ok!"! Roland: Ok. Prestley: Goodbye! Roland: Ok. bye.

You can see the reply is really annoying. Maybe this might have what your teachers might had thought "Ok" would be like.
