When an individual is forced by a governing authority to perform or attend a presentation against their will.
No I can't meet you for golf this afternoon, my boss has scheduled a 3 o'clock prisontation.
A long boring work presentation one is forced to watch without the hope of getting up and walking out. Usually involves PowerPoint and bullets and low-res charts.
John, at corporate, is making his PowerPoint prisontation mandatory for all team members.
