The phrase is Dutch playground style humour, playing on heet, meaning is called, and dinges, the everyday word used when you cannot remember a name or thing. The misspelled heeten in the title is part of how the clip circulates on user soundboards, shared as a short raar, or weird, sound rather than a clip from a known film or show. Online it survives as a tiny inside joke, posted without context so the random family reference and forgotten name feel even more absurd to anyone hearing it for the first time.
