Pro-petty

Verbal throat punch to one or many in a professional setting that allows you to keep your job. Similar to a professional "mic drop". Not rude or disrespectful however it lets them know "don't come for me".

I had to go pro-petty on my boss when our policies were questioned and they pointed the finger at me. Per your last email (see attachments 1, 2, and 3) we used your guidance to develop our current office policies. See right there where you signed off?
