Ate The Onion

The Onion is a satirical news site, they're known for satirizing the sorts of sensationalized news headlines of legacy media in the modern day, setting themselves up as an excellent critique of the absolute absurdity that modern news media can be and just how easily it is to mislead the average person.

Their headlines are typically wildly outlandish and sarcastic, but sometimes get mistaken for real headlines from actual news sources, which is called Eating the Onion.

And then sometimes real life is just a satire of itself and a real news source writes an article and headline that is just wildly outlandish people could mistake it for an Onion article, with the realization that this wild news article is not actually from the Onion, hence Not the Onion.
