It’s petering down

No, this was not said in an erectile dysfunction commercial, but rather by Heidi Przybyla on MSNBC’s Morning Joe the other day.  She was talking about the Mueller investigation.  It is a congruent conflation of “petering out” and “winding down”, both meaning to slowly come to a conclusion or end.  Another tip of the hat to Frank King for spotting this one.  He has the ears of a hawk.
