a jallen
A teacher who sleeps through class, yells at you for no reason, and gives you a zero just because you smiled at him.
'He fell asleep during the test and woke up to yell at me for not getting a question right.'
'He gave me a zero because I smiled at him and said, 'I don’t give two shits.''
'He failed me for no reason and said, 'You’re not smart enough for this class.'
