There is no clearly documented film, television or viral-video origin for Deepthroat Circus 5, and the title appears to come from a user-uploaded, numbered soundboard entry rather than a widely known scene. That lack of a single famous source has not stopped it circulating among soundboard users, who search for the exact numbered title when they want this particular clip. Its continued use therefore depends less on a backstory and more on recognition, brevity and the way the circus-themed name makes it easy to find and reuse in new edits.
