Invoking "The boosh rule" is a request to get back on task.
It originated during Run Amok recording sessions due to the natural tendency of the band and the producer to both get stuck talking about and quoting The Mighty Boosh for hours on end while they were supposed to be recording.
'The Boosh Rule' initially was a rule that was set to prevent this - no talking about The Mighty Boosh until you were finished tracking for the day.
In the time that has passed it has since spread and come to refer to any procrastination or lack of attention to the immediate task.

That silly hair that is usually sported by males in skinny jeans. A kind of mullet like style. As worn by Noel Fielding from "The Mighty Boosh"
