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.

Grant: That's such a shame. I used to like him. What a goooglewanker!
