Got to take part in TWO 5k gold lead throws today

UPDATE - I've now taken part in my 3rd 5,000 gold lead throw for the night.

Fucking unbelievable how stupid these people are.

The first one was a classic. We won every teamfight and were looking great, despite a Malphite going 0-5 against a Tryn. We had Anivia/Malphite/Sej and you'd think we'd win no problem. Nope. We push all the way to the base. Tryn starts splitting on his own. We let him go as he takes all of top lane turrets and inhib. We are still pushing and he goes for bot lane. As he makes his way to base, I tp back. No one on my team joins me despite 5000 pings. He melted me as Sejuani and basically won the game completely unchallenged. 5k gold lead thrown in the trash.

The last game was another for the books. I'm GP against Tryn. He gets a kill on me early because every top lane champ beats me early no matter who it is. I don't really die again until I take a turret. During this, he goes mid and still somehow keeps up with me in CS despite another person in lane defending against him. He picks up a few kills. Again, somehow as I clear the first 2 top turrets. Bot lane says their opponents are trolling and they win the lane easy. From then on, I have no fucking clue what went on. I take out mid tower, we get some dragons and then eventually push all the way into the top inhibs. We have just a few feet to victory.

Then it starts to get stupid. The team decides they need to 2v1 Galeo. He ults everytime trapping everyone in the ult. Tryn crits everyone and cleans up while we do this. Tryn starts solo pushing turrets because nothing can stop him at this point. He even takes elder dragon down to 7000 HP without barely any life lost. We take a Baron and the team just can't settle. All 4 of us die to Galeo/Tryn and the 5th dies soon after, losing the buff. We get a teamfight at the next baron and we lose it.

Yasuo the whole time brags about being ahead, not caring and spends as much time bragging in chat as he does playing. After his 15th death, he says "it's time to get serious". Another Galeo 2v1 and it's finally over. He takes me out along with 3 others and they push to win the game. We had a 9,728 GOLD lead and we threw it. We couldn't even group because someone would go chase Galeo or Tryn, die and then it'd be the rest of us. And with a weak ADC in Corki and Shaco, it was pretty much over. Literally, an almost 10k gold lead loss happens in something like 100 in 5,000 games. But it happened tonight.

Oh and the GP bug with him losing CS to jungle monsters is still alive and strong.

EDIT - We topped the night off with a 6K gold lead loss! I LOVE THIS ELO. I was ahead and stopping Nasus as Kayle. Our JG goes 17-3. But, our midlane grabs 78 cs in 35 minutes. I'm 2 levels above an Nasus and he crits me for 1300HP. Then, I'm 2 levels above Olaf. I go to fight and nope, dead. Anytime I split I have to retreat and the team just blows it. Also was harassed by my second pair of premades in a row for the extra fun.
