indecorum
Breach of etiquette
Indecorum is behavior that violates standards of propriety or good taste—a breach of decorum.
The word appears in formal contexts where conduct matters: The senator's outburst was an act of indecorum unbecoming of the chamber.
It suggests not outright scandal but a failure to observe expected norms of politeness or dignity.
