It's how the style of playing a particular race against another resembles the fighting style of old school fighting movie characters/actors.
I'm talking bout these dudes right hurr
When Bud Spencer and Terrance Hill start opening cans of whoopass it's almost similar to a Terran Tank-Vulture play against Protoss. A siege tank blast is much like Bud Spencer's trademark, the Hammerfist, while Terence Hill's concussive slaps, agility and urge to humiliate reminds me of a vulture harass
Here's what a push looks like when transformed into a movie scene.
For Protoss there are two fighters on my mind. Chuck Norris and David Carradine. Picture this a P [(Carradine) going reaver, being aggressive midgame and dastardly sneak dropping the main (dust in eye)] vs P [(Norris) .. it's all roundhouse kicks and fists ftw when he recovers (from the probe loss) and (storm) kicks in
I tend to think Chuck Norris is a better choice to represent Protoss in a PvZ. Lots' of storms means lots of roundhouse kicks, whereas Carradine doesn't really have a trademark move. Then again there's an awesome episode of Kung Fu I remember, when Kwai Chang Caine had to walk on rice paper without leaving a trace or footstep so he learns to walk without being heard. DT style obviously.

Last but not least Zerg.. another dilemma: Hmm. Bruce Lee or Jackie Chan?
And how about SC2? I'm thinking Jason Statham for Protoss but i don't know why.
