im new to this game, and i realized that about like 70 percent of the games that i play people are so damn toxic and say things like "ez noobs" after the match ends. Is this some sort of a meme where you do it every time when the match ends or people are just toxic? I'm starting to question now. im ready for a barrage of downvotes but i just really wanna know

Edit: thanks for the comments and tips i will surely take that into account
