FOR THE BIRDS

We say that something is "for the birds" if it is worthless, trivial or to show that it is undesirable. 

This idiom most likely arrives from the idea that birds eat very little or because they eat seed; either way, what they eat would be of no or little value to humans. 

Example 1:
   "Jayce, don't watch those reality shows. They're not realistic. They are merely sensational. It's strictly for the birds. Put on the news instead or watch a good documentary."

Example 2:
   "I can't stand this winter weather any longer. It's for the birds. Can't wait for spring."
