|1.||U Wot M8|
It is a term that British people use. People outside of the UK think it sounds ridiculous, so the modern stereotype or newfag would think that British people have very poor grammar. It basically means, "You What Mate". Those 3 words don't even make a proper sentence, therefore it is a funny thing to say and a way to make fun of Brits'
