There is no widely documented origin for Cristiii ba Cristiiii, and it appears to survive as a small user-uploaded soundboard clip rather than a quote from a film, show, or viral video. The humor comes entirely from repetition, turning a personal name into a chant that works as an inside joke. Clips like this tend to spread in friend groups and comment threads where someone actually knows a Cristi, which keeps the sound in use as a personalized tease rather than a mainstream meme.
