Refers to an unwanted "spilling over" of sound between two different YouTube contributors who are each making separate videos in fairly-close proximity to each other, and thus da mike on Person A's camera "overhears" da words from Person's B's spoken commentary, and vise-versa.
If two people want to collaborate on da making of a video --- i.e., combine da best footage-clips from their individual cameras post-production into one complete "from two different vantage-points" documentary --- they should try to film from locales out-of-earshot from each other in order to avoid YouTube crosstalk.
