Hasta la vista
Translated from the Spanish - 'see you later'.
This phrase has of course been in everyday use in Spanish-speaking countries for some time. It was used in the popular song Looking for a New Love, which was taken from Jody Watley's first album and released as a single in 1987:
My love was true
Still you threw it all away
But now you’re like the rest
Unworthy of my best
Hasta la vista, baby
'Hasta la vista, baby' came to the wider attention of the English-speaking world via the 1991 film Terminator 2: Judgment Day, 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):
John Connor: No, no, no, no. You gotta listen to the way people talk. You don't say "affirmative," or some shit like that. You say "no problemo." And if someone comes on to you with an attitude you say "eat me." And if you want to shine them on it's "hasta la vista, baby."
The Terminator: Hasta la vista, baby.
John Connor: Yeah but later, dickwad. And if someone gets upset you say, "chill out"! Or you can do combinations.
The Terminator: Chill out, dickwad.
John Connor: Great! See, you're getting it!
The Terminator: No problemo.
It is sometimes misspelled as 'asta la vista'.
