League of legends is a DOTA/MOBA game from the developer of the original map/mod to Warcraft 3 that spawned the "genre", there have been many other games like it all carrying various levels (including a little spat over the name itself) but League of legends is one of the most popular offerings in the genre itself and certainly one of the more well known entries in it. For more on the genre we high recommend the All your history show's telling of the story. Unsportsmanlike conduct in this case apparently means a type of screenlooking.... guess all those splitscreen complaints from your friends actually meant something. Source LOL!! Ha! That's my reaction. I can't stop laughing! XD.
