I was double-stabbed

The speaker was talking about someone at work who had requested something and then was later penalized for the exact thing.  It is a nice congruent conflation of “stabbed in the back” and “double-crossed”, both meaning to be betrayed.  A big thanks to Jamie for sharing this one, and who immediately recognized it was a malaphor!  Glad you shared it immediately, Jamie, as they quickly recede from the memory banks for some reason.
