Leaving do = Leaving party, Going away party
Festa de despedida

To say farewell; to say goodbye
Dizer adeus

Stay in touch (on Facebook)
Mantenha contato

Bye for now
Adeus por enquanto

See you soon

It was nice meeting you
Foi legal te conhecer

I hope that I can see you again
Espero poder te ver de novo

Bye, bye!
