I get it’s a meme, but it should be “Toxic gamers”.

A competitive game, in a competitive mode usually attracts competitive people. These people want to win, are playing to win, etc. This is the enviroment made for that. People complaing in non competitive modes are just toxic people.

But it’s also toxic to enter a competitive mode as a casual, cause a loss for your teammates, then blame it on " I just play to have fun XD".

Bad sportsmanship = toxic

Competition != toxic
