Is there an established practice of consciously categorizing one's thoughts and actions?

Is it commonly taught in buddhism to 'deem' one's thought or actions to be of a category? Example: Thoughts are about how to redeem oneself after having said something to a crush that makes us look unattractive. Then, we become aware of this thought, and categorize it as "Worrying about sexual/romantic attainments" or "Worrying about reputation", sort of "labeling" the thought. I have noticed that doing this helps me detach from aggregates, so I wonder if this is an established practice.
