Catch you on the flip flop 

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.

...we're gonna back on out of here. So, keep the bugs off your glass and the bears off your tail. We'll catch you on the flip flop. This here's the Rubber Duck on the side. We gone. Bye bye.

Jazzy on the flip flop 

Much like the Hawaiian "Aloha," a coastal Californian phrase for goodbye. Used by surfers, business men, and grocery store workers especially.

Boris: "I'll see you later"
Roger: "Jazzy on the flip flop, Boris"
