I think the other replies are missing your 'sheet' pun, from my knowledge and a quick search, I think you coined it

For a second I thought it meant the novel sheets UI Steve Jobs showed off in the original Mac OS X.

I hate to quote an AI but I got this....

>Ensheetification is a newly coined, informal term, likely from Hacker News, describing the trend where web/app interfaces become dominated by large, card-like "sheets" or panels that slide up, covering content, similar to how apps like Google Maps, Instagram, and Apple's iOS use full-screen or partial-screen overlays, effectively "sheeting over" previous views to present new information or actions.

I propose MSDS in stead, short for My Sheet Don't Stink.
