A type of walk that cocky douchebags that think they are cool and hot stuff always do. The movement of the cool walk is almost indescribable and may variate from doucheturd to doucheturd, but it is easily recognizable; if you saw it you would know it.
The key to the cool walk is that they are self-conscious about it. They purposely do it as a way to show how cool they are, but they don't recognize that it makes them look like a douchehole.
Doucheface walking down the hallway, obviously doing a cool walk: Shit dude, did you do that study guide? Shit. Fuck. I need to do it. Fuck.
Kid looking at this scene: I'm embarrassed to just look at this douchefuck.
