A business maneuver in which an employee continually sends insubordinate emails to his/her boss with the intent of embarrassment and or emasculation. Similar to the outdoor practice of slack lining it can be risky and carry with it the complete destruction of one's career.
John was really slack lining when he sent his boss an email with all the ways he had misinterpreted the sales data, luckily he copied the CEO on the email and his boss was later fired.
