I've just played a game and it has to be the group of the most toxic, foul mouthed players I've come across in this whole game.
The players I'd like to report straight to you Riot are 1) Leychel (Irelia) 2) TurtleDaddy (Naut) 3) Truly Untamed (fizz)

After we call all our roles, Leychel still locks in Irelia and goes top, and TurtleDaddy still goes jungle. Note me and Xin are already locked in, so we have two tops, two jungles, and a mid -- My friend had to keep bot lane somewhat under control.

Throughout the game we kept trying to give them tips, but Irelia, Fizz, and Naut just kept swearing at us. We kept telling them there is a chance we can win, but still no hope. I hope I spelled all the names correctly, here is a screenshot of my recently played:

I've only filed a report for the Irelia, because I planned on making this ticket hoping it can do the game some justice.

Thank you riot.
