A thing I really hate and that tilts me... but not how you'd expect

When the enemy jg or mid just spam camps for some totally boosted player and babysits them the ENTIRE GAME... knowing it will cost them the game when they could have stood a chance of winning if they'd only helped their other teammates. Like what is the point of spending the entire game in my lane babysitting a 0/5/2 toplaner who can't play ahri for the life of her and can't win a duel with a level advantage, ignite, and flash advantage? Go the crap away and help your team win elsewhere because they're losing right now but not by much. Me? I might have crap kda too, but I'm denying TWO of you any ability to build a decisive advantage and carry the game. By choosing to stay in my lane and leave your team to lose the map, the dragons, the towers everywhere else and fall hopelessly behind you are in fact deciding you would rather lose the game and just make it unfun for me than win the game and let me potentially have fun enjoying the match.

I am tilted off that, but not how you'd think. I'm not going to rage quit and cost my team a free win. I'm going to keep wasting your time, having minimal fun (some fun in knowing you're going to lose for being a camping jerk to me rather than win), and ensure my team can get a free win. I'm not tilted for my sake since my team is actually doing their job and taking objectives off the 4v3 advantage they have. I'm tilted for your mid, bot, and support who are trying their best to win 3v4 while you waste time just sitting in my lane trying to annoy and tilt me so I quit or flame my team. Go away. Go help your team and TRY to win. Choosing intentionally to lose the game just to be a jerk to me... is no better than running it down lane and feeding to ensure your team loses. Both are resigning your team to a loss that is totally avoidable just to ruin the game for someone else. I'll never understand why people do such stupid crap or how they can possibly take any pleasure from it.
