We all have pet peeves. From that coworkers who whistle, to people who don't cover their mouths when they cough and those idiots that use the word "literally" incorrectly. If pressed, each of us could make a list of a hundred things that just, well, piss us off. Right now I'm trying to catch the person who doesn't refill the ice trays at work. What kind of animal does that?! I also hate the words "guesstimate" and "ginormous" as well as the phrase "go big or go home." Ugh. Anyway, the sensible people of Reddit got together to list the biggest of the worst.
