haha... that's funny, it's really 'old' way to say it, mostly used by old people. depending on the country you'll find different ways! here in chile there's

'nos belmont' instead of 'nos vemos', making reference to the cigarettes.

here in mexico, you can say:

Cuidate, nos vemos, hasta luego, que te vaya bien

good-bye in spanish is ADIOS
when you want to good bye, you can say:
ADIOS , that is the same that GOOd bye, or simply BYE
you can say cuidate, nos vemos luego, is... take care, see you later

well is all for today,

cuidate amigo nos vemos , adios = tace care friend, see you later, bye

I once heard that during a meeting in California, the chilean president played jokes saying goodbye to Schwarzenegger with his own well-known "hasta la vista". LOL
I guess sense of humor goes beyond languages, so feel free to say good bye your own funny way.

I have an excellent one: NOS PILLAMOS!

When we are trying to say "see you later" in a funny way, my friends and I usually say "nos vemos al ratón"

Here some girls say sometimes "Chaolin" instead of "Chao".
