A parley for colleagues to out-feign each other's interest in such tedium. It is an event in which you commonly sight lockjaw, doodling, drooling, and the amazing vertical snooze. They appear to be like any other meeting. You seldom feel the sting, but once bitten it is over. Your mind is clear but you can not move a muscle.
Thoughts run rampant.
You devise little games to maintain a sense of coherent understanding but it is a losing battle. Try to take some action or cut the meeting short and the BRM embraces you with its tentacles and sucks the life out of you. If you survive the dreaded BRM, which most of us do, there is one terrible side effect. You start holding your own Blue Ring Meetings. Even though you despised the experience, the helplessness, and the pain you pass the experience of the BRM on.
