A friend of mine asked in work where one of his team was, and was told "they're in a meeting, "but it's not mission critical, so feel free to interrupt". Quite how he didn't succumb to the urge to backhand the person using such an excruciatingly bad phrase is impressive.
Luckily, where I work you need to speak clearly, in plain English due to most people using English as their second language, these buzz words and so forth people decide to spout would just cause confusion. About as close as we go to jargon is "yep, it's ******".
