Facebook Corner - A made-up corner that people think is real and they swear by

A made-up corner that people think is real and they swear by it like it's the last piece of pizza and they're gonna die if they don’t get it.

'I posted my rant in the Facebook Corner. Now it's my life.'

'The Facebook Corner is where I go to be important.'

'I got a message from the Facebook Corner. It was just my dad.'
