Abbreviation for "Not My Job", commonly used in the work place in response to tasks not related or relevant, or when one cannot be bothered. It often evolves to a double repetition - "NMJ NMJ" which rolls elegantly off the tongue.
Your Manager: Hey I want you to summarise a report for client rollout.

You: NMJ NMJ!
