The (often awkward) break in an online conversation that occurs after someone references and/or asks something which you have no idea about. The break lasts as long as it takes you to google search the aforementioned 'something' and (usually) click on the wikipedia article for it and skim-read the first paragraph or so. After the break, you proceed to pretend there was no break in the conversation, and you attempt to pass your newfound knowledge off as something you've known for ages.
Person A: Hey man, don't you love the song shutterbug?
Person B: (Bullshitting) Yeah man totally!
Person A: Who's it by again?
Person B: Uhhhhh Big Boi obviously! How could you not know that.....
When it takes someone a minute or so to respond because they are googling the reference you just made
You: One of my favorite actors is Mark Hamil
Friend: ... ... ...
Friend: Oh yeah, from Star Wars.
You: Was that a Google Pause?
A break of several seconds in an I.M. thread when one of the participants switches to their web browser in search of a pithy expression or additional evidence for some part of their conversation.
Highly skilled web surfers' googlepauses are hardly noticeable.
