Kavanuts
Used to describe someone when you start asking them questions, and they respond with constant and aggressive sounding interruptions, people like this become more and more Kavanuts with the more questions that are being asked, the angry reaction of going Kavanuts is often compared to a teething toddler with a soiled Huggie who isn't getting the kind of attention he wants
Dude! All I did was ask a question, and you went totally Kavanuts! There's no need for that!
