Every day of your life, you probably say at least one word or phrase that you have no idea came from a movie. Here are some examples:

  1. Toast – "Ghostbusters" in 1984. The classic line is "this chick is toast", which Bill Murray improvised. The line in the script was, "I'm gonna turn this guy into toast."
  2. My Bad – "Clueless" in 1995. Linguists say the phrase was probably about 10 years old by then, but was used mostly in the world of playground basketball. The movie made it mainstream.
  3. Bucket List – "The Bucket List" in 2007. This one is used so much it seems like it's been around forever, but it was invented by the movie's screenwriter, Justin Zackham.
  4. Gaslighting – "Gas Light" in 1938. The play was made into a movie twice in the 1940s. It refers to the act of manipulating someone into questioning their own sanity.
  5. The Dark Side – "Star Wars" in 1979. This one's pretty self-explanatory.
  6. Derp – "BASEketball" in 1998. It basically means something that's stupid, silly, or foolish.
  7. Catfish – "Catfish" in 2010. The documentary is about a guy who realizes the woman he fell in love with online has actually been using a fake identity.
  8. MILF – "American Pie" in 1999. This one was around before the movie, but the makers of this list say this is where it was popularized.
  9. Yippie-ki-yay – "Die Hard" in 1988. There have been plenty of variations on this phrase, going back to old Westerns and cowboy songs. The actual "Yippie-ki-yay" seems to have only showed up in Gene Autry's 1942 song "Cowboy Serenade", before Bruce Willis made it famous.
