Someone tweeted the dark meaning behind 'this little piggy' and everyone's childhood is ruined.

It's been a grim day on the internet. One Twitter user decided to spill the real meaning of "This Little Piggy," and lives will never be the same.

You probably remember "This Little Piggy" from childhood. It's a nursery rhyme that goes like this:

This little piggy went to market,
This little piggy stayed home,
This little piggy had roast beef,
This little piggy had none,
And this little piggy cried "wee wee wee" all the way home

The controversy is in the first line: "This little piggy went to market." Most people seem to have thought this meant the biggest little piggy was going out to pick up groceries.

But it turns out the truth is much darker.
