There is no spanish popular expresión. Maybe 'hasta la vista' never will be, but there are words like tequila, tamales.If I remember the movie, Hasta la vista was what the young John Conner taught the terminator to use as "hip" slang among young USA people of that area (West Coast, I think). By that time I was a lot older than John Conner was supposed to be and I don't think my friends or I ever used that. (Also, we were on the East Coast, so don't know if the expression got popular there.
