Boca

Boca is the custom of opening a conversation with someone who has a shamesticky on their karmastream, about the incident which caused the shamesticky to be applied. The visibility of the shamesticky is part of the punishment, so in extreme cases even a higher karmic won't be able to hide the shamesticky from downstreamers. The shamesticky is license for anyone to tell the sticked what they think of them, and it continues until the shamedebt is paid.
