Defecating in another human's mouth while filming one's self with two cameras. One camera positioned on the mouth of the human being defecated into to be posted on some weird fetish site. The other is positioned on the defecator's face while he or she makes a makeup tutorial. Very Meta.
The best Meta Human Bowl I have ever seen was Jim's in 2012. No one could tell he was defecating into another's mouth while he filmed a makeup tutorial. That guy's good man!
