The main place spoofing occurs in my experience is during performances, typically at bars, when the performer is trying to either set ambiance or just use a language construction that doesn't start with their own name, for the sake of variety. The spoof still has to include their name anyway.
I've never really seen spoofing for anything other than performance or ambiance setting by club employees, and the point of emoting it loudly would be the former. For context, I thought of this idea when writing a performance and practicing it and noticing that spoofs don't show up brightly.
