If you really hate someone sometimes you don't even have to say it, you can just give them a death stare and the message gets delivered. Before their UFC strawweight title fight this weekend in Berlin, the world doesn't know if champ Joanna Jedrzejczyk and challenger Jessica Penne really hate one another but it sure looks like they'd love to smash their elbow right in the center of their opponent's unblemished face.
Set phasers to death stare. If you've ever upset your significant other by using all the hot water in the morning or leaving the cap of the toothpaste tube off for 17 consecutive days you have gotten these facial expressions stared in your general direction.
