But typically you specifically "dish the dirt". "Dish" on its own is not a valid verb, at least not in the version of English I speak. I don't know why.

(Interestingly, OS X's Dictionary app says that a Britishism is to use "dish" as a verb meaning "destroy or defeat". Don't recall ever hearing this, though...)

"Dish" as a verb indicating gossip is informal, but according to Merriam-Webster (https://www.merriam-webster.com/dictionary/dish + scroll down), it can be both a transitive and intransitive verb (i.e., used with an object, or not).

Also truckstop hierarchy = social hierarchy in places where truckers exit the road to rest and receive services; and Moby Dick = an 1851 novel by Herman Melville. But "dish" is probably the trickiest thing here.

Particularly with the implication that what is being talked about is juicy insider gossip.
