“We gladly feast upon those who would subdue us.”
Not just pretty words? Well, according to Dennis of the Campvs, the Addams Family Credo might be just that: pretty words. Dennis, graduate student linguist, translates the meaning of the Addams Family movie's bit of Hollywood Latin, "Sic gorgiamus allos subjectatos nunc!":
“Thus do we growl that (our) big toes have,
at this moment, been thrown up from below!”
He then offers a possibly more accurate Latin verse:
“Laeti vescimur nos subacturis.”
