TikTok has blown up with a trend that's pranking parents across the globe in the name of Christmas.
Users have been filming themselves writing fake cards from 'friends' of their parents pretending to know them and update them on their lives - but those friends don't actually exist at all, leaving them very confused.

The reactions are gold.
