How it's used
This phrase is used to call out someone who is bluffing or acting like they have professional knowledge when they are actually clueless. It carries a slightly mocking tone and is often used when someone tries to give advice or critique something they do not understand. You will frequently hear it used when someone is caught out by a real expert.

someone who pretends to be an expert
Common mistake
Do not confuse this with 專業, which refers to being genuinely professional. Using 扮在行 implies a lack of actual skill, so it is an insult rather than a compliment.
