Mutalking

Talking away into a phone, forgetting that you have pressed the mute key.

"I'd been mutalking for like five minutes on this conference call before I realised no one had heard a word I had said."

GoogleStalk

When someone waits for you to log on to instant messaging then immediately pounces with a message..

"Man, that crazy chick in Accounts keeps sending me messages as soon as I log on."
"Dude, you've been GoogleStalked."
