Title. For me, it's Shaco. Invading at level 2 and getting FB on an unsuspecting jungler then immediately going mid to burn the enemy laner's flash puts a smile on my face, but nothing beats spamming laugh and the mastery emote in front of tilted opponents. Watching them flame me and make death threats to my mom really makes my day.
sounds like you're a bit of a dick
because child soldiers.
Me. Because I am a champion.
Nothing more fun than your lane opponent thinking he's safe with half his hp only to instantly find himself under my turret, desperately scurrying away for dear life.
Oh, what's that? There's five of you and one of me? Excuse me while I wade through all of you, pop your AD carry, then walk back out with zero fucks given. I'll be back in about 6-8 seconds at full health for your AP carry too, so don't go anywhere, mkay? :)
I love playing 
top. just stomping some unsuspecting Malphite or Darius lvl 3. hes so strong with thunderlords. Unless you get directly countered or jungler ganks, you can usually milk a few kills out of lane.
same 
Lee support by far
I really can't decide which champ it should be, so here are my favorites:
Honorable Mention: Taric top vs. Riven mains...this is one of the most satisfying matchups you'll possibly ever get on top lane. :D
, nothing more satisfying than shredding a team to pieces when that Amumu/Malphite/Jarvan IV/Orianna/Wukong ulti and dealing 
. When squishies all stand together to try to fight me, I always GENTLY teach them that there is no strength in number.
Star Galaxy 
I enjoy listening to his consistently loud and overly optimistic dialogue during gameplay..i can never seem to tilt when i play this champ using this skin!.
Sona, nothing better than making their ADC back by level 3 >:)
While I agree with Shaco as well (Hes my main). I also love playing Azir and since I play with people IRL I spend the entire game talking about the greatness of Shurima.
bc she's a queen
mid, because you are not ganking me unless you have jungle Quinn because even Zilean can't outrun that shit.
I played Mundo occasionally before he became FoTM.
I wouldn't pick him in ranked tho, I can not play serious with that champ.
Most likely, I'll show up Botlane for one simple reason: Mundo goes where he pleases.
45 cdr 
, 
,
too but I haven't played him for a long time.
because i want to be the animu hero
because my waifu has powers :D
Bard, Nunu and Braum i guess - also jihn, just really satisfying to play champs that aren´t inherently broken and have adaequate weaknesses.
Drag
them
DOWN
Ryze. Locking down enemies and annihilating squishies is awesome. Nobody expects the damage from RoA and SE. Also, he probably has the best waveclear in the game. The best part is when you QEQ and your QE sync together and instakill a group of enemies.
tahm kench :D
Sion. Because I like being a tank that builds AD. And his ult is fun.
because she's my favorite. I love to take him top and make my enemy laner tilt as they run in my shrooms and die. Ha ha XD
is a champion I'm increasingly falling in love with as I play him.
Everything is just so and when everything is right...by the time they realize they're dead it's too late.
His W is still a pain to hit though.
I had THE most awesome game with an orianna who was totally on the ball. We were positioning to dragon when three of the enemy team were running to intercept us. They step and trigger on one of my traps, try to back out...nope. Ori ults them right back on top of them. Instant triple kill.
sated, not only does he make my day, but my hole weak
Shaco because he annoys the enemy team so much and is so sneaky.lol.Lux beause everytime i play her the enemy mid lane complains thats shes broken and i always agree and say she fun too.
She was my first champion and the reason I tried the game in the first place.
he is fun when he fed.
cause you can play safe with him.
Mother. Fucking. POWERSLAM!
Playing Vel'Koz, Nami or Nasus.
I quite enjoy playing Yasuo, Zed, or Lee Sin. Something about making flashy plays really makes me feel like I'm at least somewhat decent at this game.
pai doesn't make my day... he makes my life.
Braum. I like to jump in and protect with his shield. It is fun. c: Also Bard. Cause he's.. bard.
Zed...there nothing more exciting than the rush i feel when i delete squishes from the game, ooooh i get moist just thinking about it
Nothing is like being full build at 50 min, just stealth past the frontline and obliterate the enemy mid's and adc's HP bars with 3 aa. After that easy clean up with resetting stealth and perma 70% AS buff Kreygasm
