Urgot, Cass, Karthus, Trynd, Master Yi, Irelia, Fizz, Vlad come to mind as "annoying" champs.
I would have to say Fizz.
singed, the best way to play him is to attempt to piss off the other team as much as possible
Warwick. Just stand next to the wolves in jungle, then 15 minutes into the game say, "I miss my Family. "
is actually only the second most annoying champ in the game
to induce maximum rage you'll have to play
(I hate Shaco so much that I can't even bring myself to play him despite his play style looking really fun)
