Phrases: Pumpkin Eaters

I first heard this expression in a Jethro Tull song. I have come up with my own definition; perhaps I'll follow up with some actual research to see what (if any) provenance can be determined. The phrase is the title of a 1964 movie about a woman who stays pregnant as often as she can, but I think my definition has more utility.

By my lights, a "pumpkin eater" is a gullible person, one who (figuratively) can swallow most anything, and doesn't seem to be daunted by whatever the pain of doing so is.

It helps if it fits in with prior goals or worldview, and of course it helps to have a scattershot approach to reality. Some possible examples could include: people who think all of Michael Moore's work, all the X-Files, all the utterances of a given politician, or all the Late Night Coast to Coast radio shows are great and beyond criticism.

The much-bandied term "idiotarian" is a bit more pejorative, but I'm not sure it's stronger in meaning. I like "pumpkin eater" because it hasn't become fightin' words. Yet. I think.

Note that [as I want to use it] the term doesn't denote a country bumpkin [EDIT: or does it? Etymologically, it very well might. See comments], just someone who is, as Viv Stanshall said in the spoken-word piece "Big Shot", "credulous as hell."

Eric Drexler used to talk about something he called "bogophilia". On that, more RSN.
