Stichomythia is a literary device that involves rapid-fire dialogue between two or more characters, with each line typically having no more than one or two syllables. While it is a unique term, there are a few synonyms you can use to describe this technique. One option is "verbal fencing," which calls to mind the battle-like nature of the conversation. Another possibility is "dialogue tennis," conjuring images of back-and-forth volleys between characters. "Interlocutory exchange" is a more academic term that describes the give-and-take nature of the dialogue. Ultimately, no matter what term you use, stichomythia adds excitement and tension to any scene it appears in.
