The irritating phrase repeated relentlessly by an individual who has blatantly asked you for advice or a demonstration on a given subject and proceeds then to dismiss everything you tell them (often cutting you off mid-sentence) in a feeble attempt at not appearing as unknowledgeable as you clearly know them to be; thus culminating with said individual's arrogance preventing them from gleaning any information from you whatsoever.

phrase used by an MC runner to get the lush to be quiet and get down to business
