In reference to the satirical news page, the term "onion material" is used to describe any information we receive which may sound improbable or unlikely. It is oftentimes applied to refer to a story or account which seems too exaggerated or far-fetched to be true, which we suspect may very well be bogus.
"Did you hear Jeff's story about that girl he was trying to hook up with last night? I don't know about you, but it sure sounds like onion material to me..."

"And you expect to believe that? That's onion material if I've ever seen any!"
