I've been playing this game for about 5 years now and never have I heard a champ curse before, not even the pirate 
does!
As a community member, I really do not approve of it.
Any explanation form riot on this new move would be enlightening. Thank you!
Actually Corki is pretty foul mouthed too I hear, and Ryze has always been the type of champ I would expect to hear curses from, and if GP doens't they sure should add them! Now before anyone starts the hate: you gotta understand that personality is part of the depth of the game and, while some people don't care for it, there are people (like me) who want theyr champs to be deep and consistent: What would you say if Thresh talked like a char from a child show? He wouldn't feel the same, so while I do understand that league wants to be family friendly, I think that it's just not right for a champ identity to suffer because of that.
What does he say exactly?
EDIT: He says "All this would be so much easier if I didn't give a damn."
Cursing is where you suddenly draw the line? Seriously? Let's run down a fun list of characters.
-Dead child.
-Fire zombie that wants to burn the world down.
-His ult eats people alive in a shower of blood.
-Potion addled serial killer.
-Spider monster that scarifies people to a BIGGER spider monster.
-Runs around in what is basically bondage gear.
-Raging alcoholic.
-Favorite past time is blowing shit to smithereens.
But Ryze says a curse word, and suddenly the game is filthy? Yeah, no. You're just overly sensitive.
I approve of champions cursing as well, real people curse so it adds more depth and variety to the characters. Honestly I find it awkward when some Champs don't curse! As if some of these Champs care about watching their language around others lol
yet 
can have a dam fucking cigar
what does he say?
While some champions seem like they would never curse, because they are above it (either through status or morality), it makes sense for at least some characters to curse.
