Best grime song of all time IMO. It's in the vicinity to run Sea Within A Sea down on the grass with a knife for song of the year as well.

It's just so good: the backing beat is excellent; the delivery is tense, aggressive, passionate and merciless; as lazerlife pointed out, the vocals work over everything and the lyrics are brilliant, just endlessly quotable. Video's sweet too. Plus shouting 'TEEEEEMPPZZZZZZ' while drunk has yet to get old.
