  • Il termine trae origine da uno sketch comico del Monty Python's Flying Circus ambientato in un locale nel quale ogni pietanza proposta dalla cameriera era a base di Spam (un tipo di carne in scatola). Man mano che lo sketch avanza, l'insistenza della cameriera nel proporre piatti con "spam" ("uova e spam, uova pancetta e spam, salsicce e spam" e così via) si contrappone alla riluttanza del cliente per questo alimento, il tutto in un crescendo di un coro inneggiante allo "spam" da parte di alcuni Vichinghi seduti nel locale.
