1. League of Legends. A holiday or event in the League of Legends community commemorating the anniversary of the tragic death of Urf, the Manatee on April 1st 2010.
EX. Urf was taken too soon at the claws of Warwick and the LoL community has held Urf Day every April 1st since in remembrance of the tragedy. Every year they've commemorated his demise in many different ways-- from new Urf-themed skins to special contests to charity for manatee conservation to a Cho'Gath themed game-- and this year was no different. Well, actually, this year was really different because this year we got...
ULTRA RAPID FIRE (MODE) [ul-chra-rap-id-fahyr]
1. League of Legends. A limited time game mode released as part of the Urf Day celebration, paraded comically as "the future of League of Legends", the game mode takes place on Summoner's Rift and is extremely imbalanced with Ryze and Kassadin being removed, other champions being buffed or nerfed, and the following buff being ever-present:
(Editior's Note: The mode is a ton of fun, favoring champions usually limited by their mana pool and cooldowns, EX. Sona, Soraka, Skarner, etc. I like it, but unless you pick broke champions you will most likely not have a lot of fun. I don't think it is better than normal Summoner's Rift. But it is a refreshing break from the normal game.)
And if you lose, you get a special end-screen.
