Since his introduction, Trundle went nearly two years before being subject to balance changes to any of his skills or stats. He was finally given changes in the Shadow Isles patch in late October 2012.
His quotes make several references to internet "trolls", a derogatory term for someone who intentionally annoys or offends another person.
"Don't hate the player, hate the club that's smashing your face!" is most likely a re-phrasal of the famous phrase, "Don't hate the player, hate the game". It could be also a joke from Riot implying that players focus their hate on champions rather than other players.
"How much you wanna bet I can whack you from one fountain to the other?", is most likely a reference to the movie Napoleon Dynamite, in which the character Uncle Rico at one point asks, "How much you wanna make a bet I can throw a football over them mountains?", while reminiscing of his past in football.
