People who are e-cool generally have no social life, or are completely insecure about the one they have.
They seek constant acceptance amongst their online brethren by proudly displaying every achievement of their meaningful lives for others to see. Favorite topics amongst those who adhere to the e-cool ethos include doing drugs, drinking loads and still being fine (or being hardcore, see "Ripper") or whenever they've pulled a girl. Either way, denizens of the internet mock their pathetic attempts at social interaction and proceed to flame them. The veracity of such claims is generally unfounded, which makes it even funnier when it all falls apart and turns out to be a lie.
