Just played a normal with the biggest premade trolls ever...

Normally I don`t care about normals but this 4 player premade was extremely toxic. I never said a single word in the champ select and when the game started because I didn't move right away (was in my lane when minions spawned) Lulu goes "report Talon"... All game long the Kog'Maw was talking shit and even went AFK for 3 minutes just for fun. He pings me to let him grab the red and I let him have it and say "no problem bro" and he says "I fuck ur nan".... All game long kids going through their puberty acting like wannabe tough guys cuz everyone who plays a game is nerd except them.
Worse part was they troll surrendered when we had just destroyed the nexus and they made us lose cuz "we're nerds" (said in post game lobby).

What can I do except report them which will do nothing because it was me against 4. I was nice the entire time because I knew they were a premade. You can check the chat logs and the troll surrender.
