The term 'meat sticker' is a combination of two words, 'SPIT' and 'USDA'. The word 'SPIT' is a four letter word meaning to eject saliva from the mouth. The word 'USDA' is also a four letter acronym for the United States Department of Agriculture. Together, these two words form the term 'meat sticker', which is a label that is placed on meat products to indicate that they have been inspected and approved by the USDA.
