This article is the first ethnomethodological study of rap battles. The materials for analysis are videos of battles published on the YouTube-channel of Versus Project. In the article, rap battles are analyzed in accordance with the principles of conversion analysis as a speech-exchange system. Some methods of creating and re-creating the order of rap battles are discussed. Here, “order” does not mean following the formal rules, but the situational achievement of the participants in the situation. Attention is drawn to the mechanisms of restoring order in situations of occurrence of a failure: silence, interruption, and the overlapping of turns. Examples of restoring order both by the battle rappers and by other participants in the situation (the organizer, the judges, and the public) are given. There are reported similarities and differences in the methods of re-creating order in both rap battles and everyday conversations. These battles are also analyzed as a form of institutional interaction, which has its own special features. The analysis shows how the reflexivity of the participants in the situation makes the institutional interaction without following the rules precisely possible, because the reflexivity of the participants allows the changing the rules depending on the situation without the occurrence of a failure in the order. A distinction is made between the reflexivity of the public and the reflexivity of individual members of the public. The obtained results can be useful for further ethnomethodological studies of interaction with the public, other forms of institutional interaction, as well as for studying everyday conversations.
