Back in the day, I was evidently a little “off” amongst the fishing and boating crowd I ran with. They saddled me with the moniker “Reverend” due to my given name being Jim and my (perceived) behavioral resemblance to a certain “Reverend” Jim Ignatowski of “Taxi” fame. Added a birth year and a user name was born.
Of note: I used to use the shortened version “Reverend69”, but for some reason that raised a lot of eyebrows in the online dating sites.
