Roguelike = A game like Rouge. A top down turn based dungeon crawling RPG with permadeath and randomised elements e.g. Tales of Maj'Eyal or Caves of Qud.
Roguelite = A game that takes a couple of elements from Rogue, e.g. permadeath, randomisation and some RPG systems, but usually a game in a totally different genre to a turn based dungeon crawling RPG e.g. every game GBeast calls a Rougelike because reading a couple of sentences takes much more effort than constantly complaining that you don't want to learn something.
My favourite part of Game of Thrones Season 3 was when the Enterprise hit warp and opened a portal to The Realm of Chaos from which the Blood God Khorne escaped to wage war against Westeros with his evil army of Sith and Replicants.
