Solid Jackson 

Refers to things that are very tight, like nuts and bolts. Tight enough, or also, Impossible to shift. Iced up. Milk. Engines.
We used it in our garage in the 80's.

I can't shift this bolt, it's solid, Jackson.
This milk is frozen, solid Jackson.

Solid, Jackson! 

A phrase used by be-bop jazz musicians in the 40's and 50's to compliment another's solo performance.

Your choruses on 'Yardbird Suite' were solid, Jackson!
