Thousands of WW vets got to hate Spam. It was on the market before WWII.
Spam
Trademark created by contraction from Hormel's original name for the product -- ``Spiced Ham'' -- which was copied
by other meatpackers.

n. A pressed pink pork product marketed by Hormel since 1937. It was distributed as a food supplement in the US
during the Great Depression, and to British civilians during WWII. The long-time butt of jokes; subject of a skit and song
on the Monty Python TV series.
