Subnautica is a survival adventure from Unknown Worlds Entertainment, first released in full in 2018, in which players explore an alien ocean and rely on the PDA for crafting recipes, data entries and story logs. Because checking the PDA becomes a repeated habit during long dives, short lines connected to it are instantly recognisable to fans and work as shorthand for looking something up. On soundboards and in gaming edits, the clip is now used less as a literal game instruction and more as a knowing joke about tutorials, guides and information players already had.
