truckin'

Truckin' is an informal spelling of trucking that captures the dropped g of casual speech.

It means moving along or making progress, often with a sense of steady, unhurried momentum: Just keep on truckin'.

The phrase gained countercultural currency in the 1960s and 70s, associated with R.

Crumb's iconic cartoon character and the Grateful Dead song.

While it can literally mean driving a truck, the figurative sense of persevering through life predominates.
