@oristarA,
Hasta La vista
Meaning
Translated from the Spanish - 'see you later'.
Hasta la vista, baby' came to the wider attention of the English-speaking world via the 1991 film Terminator 2: Judgment Day, which was written by James Cameron and William Wisher Jr.
The phrase features in an exchange between the film's characters John Connor (Edward Furlong) and 'The Terminator' (Arnold Schwarzenegger):
In this instance (hasta La bye bye) the speaker combines two languages to reinforce his determination to finish doing something (whatever it was.)
Finito Is exactly the same. (Possibly of italian origen)
