Deadpool and Wolverine might mark the first time the titular heroes have officially been in a MCU movie, but the Merc with a Mouth and gruff-talking mutant aren't the only things the film is introducing to the franchise. There's Matthew Macfadyen's rogue TVA agent Paradox and Emma Corrin's Cassandra Nova; there's the word "pegging", and there's also... the term 'anchor being'.
The phrase is uttered early on in the threequel, as Paradox explains to a wide-eyed Wade Wilson (Ryan Reynolds) that his timeline, confirmed to be on Earth-100005, is dying thanks to the death of Hugh Jackman's Wolverine.
