I’m trying to track down a sketch I remember from the early 1980s - possibly from the ABC show Fridays.

It was done like a news report. A young man claimed to have invented a new swear word ("carkfum" or something similar). The reporter asked how it was used, and he said things like "carkfum this, carkfum that, kiss my carkfum."

As he kept saying it, the people around him became increasingly offended and ended up attacking him (played for comedy).

Does anyone remember this sketch or know what show it was actually from?
