People who do their hardest to try to tilt their teammates.
Are you sure this is their intent...
They'll passive aggressively ping all game, flame you the entire game,
Pings are mutable, chat is mutable...and maybe they're just helping to communicate
smite buffs away from you, smite cannons away from you, etc. for literally no reason.
So if they're smiting a buff they are probably the jungler and it's their buff? It's kind of an etiquette thing to ask if you're going to take a buff from a jungler.
A cannon minion can be smited in the interest of pushing the lane out quicker.
You can be playing perfectly, be the most positive player on earth, and still have people do this. Why do people do this? What's their end game?
Maybe they're just playing the game the want they want to play it.
