The term "Hasta la vista", literally "Until the view", is a Spanish farewell that can generally be understood as meaning "Until the (next) time we see each other" or "See you later" or "Goodbye".
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 up to you with an attitude, you say "eat me". And if you want to shine them on, it's "hasta la vista, baby".
