'Ta com soninho' is a common colloquial Brazilian Portuguese phrase, built from 'tá', the everyday short form of 'está', and 'soninho', a tender way to say a little sleep. The clip has circulated as a short shareable audio rather than as a line tied to a known film or show, which helped it fit many private chats and edits. Its popularity comes from timing and tone: it works as a caring check-in, a gentle tease and a bedtime sign-off, so creators reuse it whenever someone on screen looks ready to doze off.
