Pob comes from Pob's Programme, the British children's television series that ran on Channel 4 in the mid 1980s. The puppet character opened episodes by breathing heavily on the camera lens until it misted over, making a spitting raspberry noise, then tracing his name in the condensation with his finger. That opening became the thing British viewers remembered most, and clips resurfaced online decades later as nostalgic memes. The spit moment now circulates on its own as a rude, funny reaction sound detached from the show.
