When your dick goes limp during anal but you keep jamming it in there

Bro, I was power driving Jessica but the blood flow killed my boner, so I ended up giving her a dirty slack

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.

Slack Block

Prevention of someone else's ability to slack off. At work, if your computer is being repaired, but you are offered a loaner to continue to be productive, the IT guy 'slack blocked' you. If at home, you're significant other presents a reasonable request to do something, that prevents you from vegging.

My computer is being worked on by IT and I thought I'd have the afternoon off, but they slack blocked me with a loaner machine.
