People who play one-button-winners and then gloat like they actually did something.
The worst thing in the world is for some Jhin or Annie to pop off and then suddenly they think they're diamond. Like, do people not realize that champions like that do all of the work for you? You literally have to do nothing except not die and you auto win the game simply because you deal almost 5k DPS in a fight. Champions like that win by not dying and you one shot everyone on the enemy team, regardless of what your build is. I have no idea why these Jhin players right click and one shot someone with a 3k base auto attack and then type in all chat like they just made some LCS Faker play.
What is with this Bronze ass mentality where people think their champion means their skill. When you pop off on Annie, when you pop off on Jhin, it's because your team is carrying you HARD and you're allowed to spam your buttons and kill people with absurd damage. It does not mean that you're skillful or even proficient with a champion. I see Mastery 7's feed in a winning lane 0-13 and someone first-time play someone and go 20-1 and get a pentakill. Yasuo is another good example. In Gold and below, Yasuo is a right click to win champion and he auto wins by simply having a higher attack speed. It's not until you get into Diamond where you actually have to use your brain, but just because people say, "Yasuo takes skill" these Bronzies pop off and think they're LCS material.
If you wanna gloat about skill, play Azir, play Galio, Play Warwick and pop off. Legitimately weak champions where you have to do something with a brain to be effective. Don't play Jhin, Annie or Yasuo with level 2 one-shots built into their kits.
