After being told off for idiotic behaviour, and the teacher claiming said pupil was in fact NOT idiotic, he was instructed to complete 100 lines on the black board located at the front of the class room so all his fellow students could see. The 100 lines were to read " I am not an idiot" he then proceeded to write 100 times:
I AM NOT AN IDOT.
Often used to call people a idiot or just as a general derogatory term
That guy sure is an iDot
