Catch you on the Flip

A saying by Alponse Garcia. Copyrighted in the 1900's by his grandfather Jake Garcia. Also "Flipside".

Catch you later.
Invented by Mike Regis

A phrase coined during the 1960s and 1970s trucker Citizen's Band (CB) culture. It literally means "I'll contact you on the return trip." If two long-haul truck drivers regularly make opposing trips, their path will eventually meet on each iteration of the trip. This term is virtually interchangeable with catch you on the flip side.

See you later
Talk to you soon

Generally, "see you later."

The "flip side" is the reverse side of a vinyl record, a term often used by radio DJs. They might say "I'll catch you on the flip side" to mean they will let a particular album play through, and won't start talking again until they have to change or flip records.

"flip flop" is a variant used originally by truckers to mean a U-turn or the return trip, and may be used instead of "flip side."

In the early stages of spaceflight, NASA developed a technique that saved much needed fuel to return space craft back to Earth by using the moon’s orbit like a slingshot. Astronauts in space and ground control would lose radio signal once the space craft makes its way to the “back-side” of the moon and away from line of sight with Earth. They would of course regain radio signal when they reach the other side of the moon (the “flip side”). It was customary for Ground Control to say “Catch you on the flip side” before they would lose radio signal.
The none-space working-class community adapted the phrase as a “good-bye” or “see you later.”
