A term often used to reply to an internet troll, who is quite obviously trying to bait the other side. Another variation consists of "gr8 b8 m8, I r8 8/8".
-In a random fandom-

Guy 1: "Who's your favourite character? I like *Insert popular character* because the dude's really cool."

Obvious troll: "No way, *Insert most hated-by-the-fandom character here* is the best character. All of you are ignorant pricks."

U Wot M8 is just text slang for ' You what mate?' - a confrontational phrase used mainly in Northern England. Normally in response to another confrontational phrase - see example below. It does make sense though is abbreviated, it is a shortened of "YOU are going to do WHAT, MATE?" Mate being the obvious indicator that there is trouble afoot. This abbreviation is probably the cause of much confusion to the American audience since they have similar difficulty with 'half two' meaning half past two (not one or one thirty like some of the common guesses).

Mostly used after getting good kill or shot, in mostly FPS (1st person shooter)
Rekt is a misspelled version of the word "Wrecked". M8 is meant to be M + Eight = Mate. So it's get wrecked mate
