Bash - Choking the system - Fork bomb

This is a wicked post. If you execute the script given in this, then you would need to restart the machine. The command:
:(){ :|:& };:
What does this mean:
:()
{
 : | : &
}
:
It creates a function called : and then calls the same recursively in the background. This would cause the system to choke due to continues creation of processes. This is called as a fork-bomb. Fork-bombs can be created in many languages/ways. Check this Wikipedia page.
