All the pricks came out of ranked and flooded normals when the season ended

I played 2 games since the pre season started. The first game everyone was telling each other to kill themselves and flaming for doing poorly (ofc they will do poorly its not even 1 week into the pre-season and people are testing out new things). The second game I asked my top laner to help me leash and he said "fu". When I asked "why are you not leashing" my mid laner told me to "stfu". Is it just back luck? What is everybody's problem?
