Greenscreen
A fake backdrop — and a metaphor for any obvious fabrication of context.
Origin
Chroma-key compositing, in which actors are filmed against a saturated green (or blue) backdrop and any pixels of that color are replaced with a separate image, has been a film standard since the mid-20th century — but the green-screen version became dominant once digital compositing arrived. The metaphor — 'looks greenscreened' for something visibly artificial — followed.
Modern usage
Used skeptically about any video that looks staged, and about claims that ignore real-world context. 'He's giving a greenscreened version of events.'
