Ubbi dubbi is a language game spoken with the English language. It was popularized by the 1972-1978 PBS children's show Zoom. ... Ubbi dubbi works by adding -ub- /ʌb/ before each vowel sound in a syllable.
I was exposed to this game from Zoom, but didn't actually learn how it worked until early high school.
From the Language Game wiki article, it looks like there is something called Fanqie (反切), but this doesn't really feel like a language game in the same way Ubbi Dubbi does; Ubbi Dubbi is spoken just for fun (or maybe to be slightly secretive, but native speakers can often understand it even if they don't know how it works)
Are there games like Ubbi Dubbi for spoken Chinese (preferable Mandarin, but would be interested in general)? Any audio or video examples?
