The title refers to anthropomorphic dinosaurs, meaning dinosaurs given human traits such as speech, and to ciao, the informal Italian word used for both hello and goodbye. No reliable source artist or original programme is credited for this short clip, so its life is mainly online as a shared soundboard sound. It circulates in Italian language meme edits and short videos where a quick spoken greeting is needed, and its appeal comes from the simple mismatch between a familiar everyday word and speakers imagined as dinosaurs.
