Your exobrain (or exo-brain)is your extended brainpower from the information you have access to from your computer or the web.
This is most commonly used in meetings or on calls when the other people don't know you're using your exobrain to pull random facts or figures.
I stunned the meeting when I knew that the first person to use the @ symbol for email was Ray Tomlinson by using my exobrain.

Thanks exobrain and Google!
