The line comes from To Catch a Predator, the Dateline NBC series in which Chris Hansen confronted men who arrived expecting to meet a minor and questioned them on camera before police intervened.

As a meme sound, it now works as shorthand for exposure, letting creators imply that someone has been caught without explaining the original investigation.
