I'm outrageously bored during this conversation
Really? Am I boring you?
I have to complete projects for class tomorrow.
Even if you are personally feeling disinterested in a conversation, it's very rude to call it outrageously boring since it is very judgmental and an attack on the other person. You should try to be more considerate towards the feelings of others to prevent them from feeling bad about their actions. If you feel that a conversation is boring you should try to make it more interesting by changing the subject.
You're stupid if you even think about getting into conflict with me.
Rudeness is no excuse. Can you tell me what classes you are taking then?
