Sounds like a sad life if you invest so much time for trolling people you don't know but whatever...

Well you could say that. Yeah sometimes your team mate will sabotage the game the first instance of cheek or disrespect he gets from you in the chat. Sometimes even from the style of your play. Other times they will just go afk and jump on their upside down and spin around or drive around not playing the game. It doesn't annoy me because I get more ball action with them playing but you could definitely class that behavior as toxic. 

I've recently bought Rocket League and thankfully the community so far has been fun and not filled with toxic annoying douchebags.

where did you play football? to shootout some not so nice words  in moments of heat is absolutly normal nobody ever says something and after the game everything is fine.

How could it be "toxic trolling" to tell a camper in your squad in battlefield to stop fucking camping and push trough the flag? he is trolling and toxic for the whole game because he let his teammates die only to snipe from far away. he just should get banned from xbl or psn for a view days because of camping, or the people who join rounds but dont play only to gain xp at the end of a round.
