Gadabout Gaddis's birth name is Roscoe Vernon Gaddis.

It implies someone who travels around a lot, not necessarily derogatory- Gadabout Gaddis was a popular radio and tv fishing commentator. He was often televised fishing out the bow hatch of a Republic Seabee amphibious plane-which tied into his TV show- the Flying Fisherman. Opposite of Gadabout would be a Homebody or a Porch-rider.

Nope, they are two different people. The flying fisherman's name was - Gadabout Roscoe Vernon Gaddis.

Gadabout Gaddis was born on January 28, 1896, in Mattoon, Illinois, USA.

Cowboys loved a colorful phrase! This meant somebody who walked around without any business or job. They just loafed about.
