Microscoping

Calling attention to a small detail or attribute that bothers you about someone, or asking them to explain it to you on the spot. Usually something that most people would avoid out of respect, or overlook because of how unimportant it is, especially when done without any segue and derailing the conversation or ruining the vibe. May be done intentionally to "knock someone down a peg", or unintentionally due to social retardation. The chosen detail may be an insecurity for the microscopee, or may become a new insecurity after the microscoping is complete. The chosen detail may cross a line, leading others to callout the microscoper, or it may be too subtle to warrant a callout.
