Slack jacking

When someone takes over a thread on the Slack messaging app for their own purpose

I was talking to Mark in the update channel in Slack and the entire sales team decided slack jacking would be a good idea to discuss how to sell it.

jack marin

Jack Marin is the 'fun coordinator' for the band Hellogoodbye and was also an assistant to the boys of Panic! At The Disco during one of their tours.

He is known for dressing up in hot dog suits, banana suits, carrot suits, chewbacca suits, etc., while running on stage of a Hellogoodbye performance.

He is also a sexy beast.

Jack Marin in a banana suit makes my heart go thump thump.
