What are the definitions of fun and attitude in LoL ?

So , i've have played in two matches , both were winning , but it got me thinking about "fun" and "attitude" ( i'm not native speaker so sorry if i make a mistake ) . Here how it goes :

1. All for one , 5 Malphites vs 5 Yasuos ( i am in Malphite team ) , we were owning them and destroyed their middle ihibitor , i told my teammates all mid to finish the game , but they refused . Instead , they went and did some stupid and unnessary stuffs keep the game longer and longer like 1 vs 4 , 2 vs 5 , solo turret without minion , dancing at turret , etc ... in their view , it was fun and enjoyable . The Yasuos then countered , aced us and push bottom lane but we won in the end. After that i get reported and being called a bitch , "leader" , "%%%%" . Who was right and who was wrong ? Me or my teammates ?
2. Normal Game , I was Braun Support , Zyra , Jayce , Rengar and Tristana vs Zed , Mundo , Lux , Ashe and Sion . This is the second time i played Braun , so i knew i suck hard . we were losing early game and Tristana goes flaming us , said all na player were all trash ( i don't mind it because he's right , i'm a trash from the moment i play LoL , can't play all champion which is the requirement for decent player , never pick adc because i suck ) . After that , we went grouping and aced them 4 times . The third time we aced , Zyra , Jayce , Rengar were alive and pushing . But then Jayce and Rengar didn't destroy the nexus turret , instead they went solo top turret without minions and got them killed . I complained why don't hit the nexus turret then they said no , i don't have the right to say that because they are carrying ( even though i was 2/7/27 saving their asses ). We aced them again at Baron , Rengar died , Jayce and Tris go Red and Blue Buffs , Zyra and I went destroy the nexus and won the game .Before the nexus destroy , Rengar said "don't win this game early" , " we're having fun" . What the hell ?

So anyways , can you guys share your view about "fun" and "attitude" in LoL , because this might help me to stay in my favorite game
