This was heard on MSNBC, Jansing and Co. show. There was a discussion on civility in America and this malaphor was uttered. It is a mashup of “disappear before out eyes” (suddenly no longer visible) and I think “out of (someone’s) hands” (no longer in someone’s control). “Slip through (someone’s) fingers” might be in play, as it also refers to something missed or escaped. Fingers and hands are close in proximity. A big thanks to “Eagle-eared” Frank King!
