So much hate, let's lighten the mood. I'll start.
Going jungle in a game where all your lanes lose and you obviously get the worst of it for some fucking reason only to report the dumb asses and get paired AGAINST them next game. Obviously you win...and report them again.
Most my high points are on 
1v1 enemy champions from 100% to 0. Stunning idiots who don't know 
is coded as terrain. Landing a cluch ulti where I just edge the melee champion abusing my adc or mid with out locking them down. Hitting folks off minions in a moveing wave. Pissing friends off by making it to higher ladder MMR going ZZROT Botrk Bard when they FOTM copy and paste pros and streamers.
Playing with previously mentioned hommies and winning games doing stupid shit like Displacement comps 
5 support champions. 5 man 1 lane push to inhibitor.
Adc kindred when you dominate lane mechanicaly and have fat stacks and massive AS and Range and W pokes out champions from under towres for 600+ damage.
counter jungling.
Generally improving on folks or every time I can find a viable for me off meta build on anything.
Pentakills.
Pulling off a crit phantom barrel and oneshotting the squishy target. Yayeet.
When I get an instant feedback message after I got harassed in a game as the jgler because all lanes lost. Fight for my scuttle and maybe their jgler wouldn't have a level advantage. :)
Landing the last shot or playing the game with my friends in general...
