what does it mean when they say to chaulk a nut

[DireWolf]

Hmm I was thinking it was like "chalk a nut" like you'd chalk a que stick. Only this was a phrase used similar to 'cowboy up'. So, chalk your coin purse and saddle up for the ride!

I had a chaffing/Gold Bond suggestion, there, too but was afraid to throw that out there.........
