Hasta La Vista, Baby

This is it, two fighter are at each other throats. Finally, one side, often the hero, has the villain right there. Now, it was time for any last words to give to the defeated enemy. What better phase than, “Hasta La Vista, Baby”? Popularized by Arnold Schwarzenegger in Terminator 2 (although it was used five years earlier in the song “Looking for a New Love”), the phase, along with variations, is often used as a way to end a confrontation or rivalry. The term, Spanish origin, translates to “Until the (next) sighting” or “See You Later”.
