I made i_am_thirsty_ ragequit!
If you play on Playstation in North America, you probably know who this guy is. He's a griefer who joins lobbies, camps an item box, and hits you with missiles and masks as you pass him. I've been encountering this guy for years. He'd started targeting me specifically while letting others pass.
Rather than quitting, I've turned it into a game over time. I pick fast tracks if possible, try to get a good item, and hit him before he can hit me. I'll let second place go ahead to hopefully draw the missiles, and try to hit him. Shields are the best item obviously.
Suddenly, the past few times I'd seen him he hadn't been targeting me at all for some reason, instead going after others. Maybe he gave up?
Today in Sewer Speedway, he was by the left set of item boxes after the start. I go to the right, turn around, and hit him with a shield from behind while he was bullying somebody else. And then he left the game!
This is legitimately the first time I've ever seen him leave a match. Maybe it was just a fluke and he just had to leave. Maybe his mom put him in time-out, who knows. It sure gave me a laugh, at least!
Sadly I saw him again a few matches later and he's back to targeting me. Guess he's mad again. Anyway, it's a fun game, I encourage you to try it sometime.
And thirsty, if you're reading this, your camping spot in N. Gin Labs sucks. You should be at the end of the barrels.
