SPAM(This article is about the canned meat, see Spam for alternate meanings)
A Hormel official once stated that the original source of the name SPAM was "Shoulder of Pork And haM". Other explanations of the origin of the term include "SPiced hAM", "Spiced Pork And haM", "Specially Processed Army Meat", and "SPAre hAM." The current official expansion is the acronym "Specially Processed Assorted Meat" because the SPAM Lite variety contains both pork and chicken meat.
According to Hormel's trademark guidelines, you should spell SPAM with all capital letters and treat the mark as an adjective, following it with a more generic descriptor, for example "SPAM luncheon meat".
Not everyone likes SPAM cold, which is how you would eat any other luncheon meat. Fried SPAM is popular amongst many people.
Also of interest is a small local festival in Austin, MN, USA where Hormel corporate HQ is located. The even, known as SPAM Jam is a carnival type celebration which coincides with local fourth of July festivities, featuring parades and fireworks which often relate to the popular luncheon meat.
