The full form of "OT" in chat typically means Off-Topic.
When used in online conversations, "OT" indicates that the current discussion has strayed away from the original subject or intended focus. It's a common way to acknowledge or point out a tangent, often with the implication that the conversation should be steered back to the primary topic.
For example, if a chat group is discussing a project deadline and someone starts talking about their weekend plans, another participant might type "OT" to signal that the conversation has become off-topic.
Essentially, "OT" serves as a shorthand way to maintain focus and relevance in online discussions.
