Possum
Pre-takeoff checklist
I started flying in the '70's when the CB radio craze was at it's apex. Slowly, the CB lingo such as "good buddy" or "hammer down" started creeping into aircraft radio communications. It was fun while it lasted but I remember one on the flying magazines had a big spread on the proper use of radios and how CB lingo was toxic to aviation communication. We didn't use headsets back then so it was a challenge to hear much of anything from the radios.
