This ditty was uttered on July 20 by Stephanie Ruhle on MSNBC’s “Velshi and Ruhle”. It is a nice congruent conflation of “at arm’s length” and “keep at a distance”, both meaning to keep someone from becoming too close. Perhaps a “distance” is farther than an “arm”? I imagine that fits in this context. A big thanks to Frank King, the Mental Health Comedian, for hearing this one and sending it in.
