"Kicks like Bruce Lee on a bad day."

From Digital Alterity Wiki

Phrase containing an unusual simile once uttered with frightening regularity by Rusty Haskell. The term has fallen out of common usage because it's painfully stupid to contemplate.

Origins

The phrase almost certainly started being used in a personal journal which Rusty kept in Microsoft Works from the moment he got his first home computer, a Packard Bell 486SX/33. The simile is based on the notion that Bruce Lee kicks incredibly hard -- or at least that he did kick incredibly hard when he was alive. The prepositional phrase "on a bad day" was meant to imply that Bruce Lee would be particularly irritable and more likely to kick the living shit out of you on a particularly trying day. Of course it could also imply that Bruce Lee wasn't up to par, implying that the kicks were in fact from a gimpy Bruce Lee. And no one wants a gimpy Bruce Lee.

Integral to this statement actually making its way into common conversation is the fact that the verb "kicks" can be regarded as positive, cool, and totally bitchin' according to some version of slang that this correspondent is too lazy to research a name or classification for.
