Faldage sez: "The Latin verb is calumniari."

"Calumniari" is actually fried squid, served, in the Italian fashion, with a red sauce, or in the Greek fashion, with a lovely sauce based on unflavoured yoghurt, garlic, olive oil and lemon juice.

To "calumniaricize" someone is therefor to offer them some deep-fried squid with a nice sauce on the side.
