Somebody that gets off on all things google and can't wait to get "Buzzed", catch a "Wave", and experiment with the latest lab result. This person usually has stained posters of Sergey and Larry in their bedroom and has collected every different google.com home page image and compiled it into a bed sheet that they use to wipe off the results of their excitement.
After Google Buzz was released Jon, a frequent googlebator, announced the death of twitter and all things social.
A Googleator is a tool used to search for something on the internet. This is a generic term typically used when asking someone for a device to search (without having to ask for a "smart phone" or "tablet" or "laptop" or whatever). It simplifies the question without having to worry about what type of device they have.
