Going on tilt is a gambling term that is basically losing a few games and getting salty. Then playing more and more to turn the odds back in your favor until you inevitably end up much worse than where you started.
So today hasn't been the best day in ranked for me. Dropped 3 matches in a row and a little over 100 points and the familiar feeling of "Going on tilt" is coming back. Luckily I've experienced it before so I'm just gonna stay away from the game today so it doesn't get worse. (Probably, it's only 11am. I mean how much worse could it possibly get >.>)
Anyway, that isn't even my worst tilt story. The worst was in the first ranked season. I was ranked fairly high, probably around 10th-20th and I think Mill had just started getting popular. I generally used FD mixes back then and wasn't familiar with the deck. I proceeded to drop 8 matches in a row to the damn thing. Each time thinking that it must be some kind of fluke....it wasn't, and I was being an idiot. By the end of the day I was down around 400 points for ranked. Learned a good lesson that day though.
So what's your worst story of going on tilt? Doesn't have to just be ranked. Doesn't even have to about IW. Just talk about one of those times you just wouldn't throw in the towel, and wound up feeling like an idiot.
