Nutty slack 

Ooooooh! I'm so annoyed people keep getting this definition wrong!

Nutty Slack is a hard toffee containing Brazil nuts and or peanuts.
I was trying to explain to my daughter what it was and she thought it was a swear word,
Back in the day you were dammed lucky if you got a small piece in your Christmas stocking for Christmas.

Although it is true that the nut would be almost whole when you had a poo but surely that was a small price to pay.

Wow! How lucky am I! A chunk of nutty slack for Christmas.

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.
