What does it mean...?

.... on the pork rinds label - "Not a significant source of protein" right under the 8g protein per serving. Does this mean it's sort of junky, worthless protein? Just wondering - it's always mystified me....

I have wondered the same thing. One thought I had is that it is not a nutrient dense food (i.e. vitamins and minerals) and conventional wisdom would say it is bad because of the high fat content, so maybe it is more like a disclaimer so they don't get in trouble from someone claiming it is a health food. Just a thought.

From another website:

"Protein": A statement of the number of grams of protein in a serving, expressed to the nearest gram [...] When the protein in foods represented or purported to be for adults and children 4 or more years of age has a protein quality value that is a protein digestibility-corrected amino acid score of less than 20 expressed as a percent, or when the protein in a food represented or purported to be for children greater than 1 but less than 4 years of age has a protein quality value that is a protein digestibility-corrected amino acid score of less than 40 expressed as a percent, either of the following shall be placed adjacent to the declaration of protein content by weight: The statement "not a significant source of protein," or a listing aligned under the column headed "Percent Daily Value" of the corrected amount of protein per serving, as determined in paragraph (c)(7)(ii) of this section, calculated as a percentage of the Daily Reference Value (DRV) or Reference Daily Intake (RDI), as appropriate, for protein and expressed as Percent of Daily Value. When the protein quality in a food as measured by the Protein Efficiency Ratio (PER) is less than 40 percent of the reference standard (casein) for a food represented or purported to be for infants, the statement "not a significant source of protein" shall be placed adjacent to the declaration of protein content.

In other words, the amino acid composition of pork rinds sucks. Pork rinds are considered an incomplete source of protein because they contain very low amounts of some essential amino acids.
If your question is "should I count this towards my macronutrient minimums?" then no, you shouldn't.
They're a source of Protein; Just not a very high or valuable source.
