That’s for the birds.
The origin of this phrase is believed to be from the observation that birds tend to peck at animal droppings to find seeds. Something that’s “for the birds” is as insignificant or unimportant as the undigested seeds found in the ubiquitous early 20th-century horse manure.
It’s not worth considering seriously.
But those worthless, manure-embedded seeds are important to the birds. In fact, its what keeps them alive. It might be their only source of food.
Just because one person thinks it’s for the birds doesn’t mean that it’s true.
