Annoying champion sounds

I almost never mute player chat when people are toxic. I really don't care that much, However I find it most annoying when players spam sounds like laughter or their taunts/ jokes. Is it possible to somehow mute those sounds? For example I more than once played an ARAM game where i had to listen the entire game to the words "My right arm is alot stronger than my left arm". Also can you report people for doing this?
