Jehova's witnesses.
I hate people with mono-brows. I really hate these people.
Their mono-brow makes it very difficult to gauge their facial expression. You cant tell when the ma'f***er is frowning, so its incredibly difficult to get away quickly or to see you are about to get murked. It happened to me once. We were chilling at newscafe with a couple of random broads and a dude i hardly knew that had a mono-brow. So naturally, the rest of us normal humans beings began to mock the mutant about his unusual and funny deformity. His expression didnt look like it changed the whole time...even as i lay on the floor, getting kicked in the teeth by him, i struggled to see a change in expression on his face. f***ing Klingon.
