Like Spaw, I always thought that word should be "stroker." I have no idea what a "hot rod stoker" is. I would venture that neither does Hank (nor possibly the songwriters).

One detail on the chord sequence found in Sorcha's Cowpie link--in the second line of the bridge (on the words "fun" and "two"), come back to a C chord; then go on to the D7 (or D) chord to begin the third line.
