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."

The none-space working-class community adapted the phrase as a “good-bye” or “see you later.”
With that being said: “I’ll catch you on the flip side!”
