Then there's "16year girl full." That part sounds like it's referring to a 16-year-old girl in full, possibly a character or a person. But the combination of terms is confusing. The user might be referring to a specific app, a mobile game, or even a nickname. Since "pappu" is sometimes used as a term of endearment in Indian contexts, maybe "pappumobi" is a nickname for a mobile app related to lentils? That seems unlikely. Alternatively, could it be a mishearing of "Papaya Mobile"?
