Where did the name TRICKY come from?

Tricky: Krust! Do you know Krust? There's a place called Broadwalk Shopping Centre, and when I was about 15 I was supposed to meet him there. But my uncle from Manchester had come down and I got in the car and drove straight back to Manchester with him. About six weeks later, I come back. My uncle dropped me off at Broadwalk... and Krust was there. It was like he'd been waiting there for six weeks! So he says, 'You tricky bastard!' And that was it... I got the name.
