How to reply when someone uses “roster” in a chat: Match the speaker’s register (informal conversational). If they are joking or exaggerating, a brief acknowledgment (such as bet, no cap, or grand) fits; if the message is in a professional channel, reply in plain English: “Everyone in the chat understood the informal expression (a rotation of several casual dating prospects someone texts or sees simultaneously before choosing to commit to one.), though we used standard wording in the formal report.”.
