Multi-slacking

Engaging in many small activities at once, none of which are productive. Usually, but not always, involving a computer and its applications (iTunes, AIM, YouTube, etc.), can also include watching a movie or TV show, listening to the radio, talking or texting on the phone, or any other ultimately trivial, meaningless activity.

That dude was multi-slacking like mad when he should have been working.

slack jaw

Dropping the mouth open and leaving it open for a time period in astonishment or amazement.

When I got the bill for the $5000.00 she put on my card for clothes at Nordstrom, I was slack jawed.

slackdaddy

A master slacker. One who excels at the art of slacking, to the point that it appears a serious effort has actually been made.

A slackdaddy invites slackers over to clean his place, and they will, without ever realizing a serious effort has actually been made.
