Kwophobia
The sudden unpredictable hatred of people. Everything can be awesome and then suddenly the feeling of hatred of people will take over. In extreme cases, those suffering from Kwophobia will feel a strong need to stab people in the neck with an air filled syringe.
You see someone squinting and as them, hey what's wrong? They then say, I just had a conversation with Chuck. He is so stupid and now I'm suffering from Kwophobia.
