Is this what "tilting" means?

I dunno wtf is going on the past few days, if it's at all related to the start of the new season or just dumb luck, but damn it's getting trolly. I dropped from 1291 to 870 on lolking over the past 4-5 days. My win rates have dropped from 60% to 35%. I've failed personally in a few of these matches, but some of the match-ups have been ridiculous. I've had game after game after game of having 2-3 unranked teammates and/or a bronze while I was silver 4/5, against teams of full silver 3-5. Mind you a lot of this was before the reset. I usually main support (80% win rate with Nami before all of this), but I've had the displeasure of one ADC after another not understanding basic shit about their role and how to work with the support (not pushing lane without vision, not tower diving at level 3, letting me last hit cannons with charges, overextending alone like crazy, etc.). Anyone else having a really bad streak at the moment?
