Slack-a-lack

The art of initiating a Slack conversation with a co-worker, typically based off of a previous conversation with a different co-worker.

I was looking for information on that project, but thankfully Sam Slack-a-lacked it to me.

Slack batter

Man, I had no idea whether she was a minger or minter, and still couldn't work it out after I slack battered her chin ...

slack fatigue

Pro Slack

Inherently the Man with the plan. One born with original slack that transcended slack itself to reach pro status.
One who has not descended into false slack at any point, ever.

Wow, everything is falling into place, just like it should, talk about Pro Slack. The pieces are falling into place, the cards are thrown, onwards and upwards, non stop to the top. This is the way I had it planned, I'm Pro slack baby.
