Zoomlighting

Working on email, phone or generally being distracting while attending a conference call you're meant to be on.

Being found out for emailing one of the conference call participants on a separate matter, while being on the same call.

Janet was zoomlighting during the budget call - she emailed Brian her leave requests while he was making his presentation.

I can't believe you zoomlighted me man! Have some respect, I could hear you talking to Global INC as your mic wasn't muted!
