SUPGRL Cut Me Off

Yesterday while I was driving through the Chicago Loop on the Dan Ryan Expressway, SUPGRL in a red Kia switched lanes into my lane. Right in front of me without giving any notice! In the vernacular, she Cut Me Off. Don't worry, there was no incident and I have now recovered from that one's lapse in politeness.

But of course I (like you) wonder whether SUPGRL is aquainted with SUPADAN...
