  • Picture a bright flash of lightning crossing the sky or a metal screw holding a door closed tightly
  • It's the feeling when you suddenly jump up and run because you are surprised or scared
  • Sounds like "bolt" → imagine a strong arrow or lightning bolt shooting straight and fast through the air
  • Remember cartoons where a character "bolts" out of a room when scared or surprised—fast and sudden
  • NOT like "run" (which can be slow or steady), "bolt" means very fast and sudden movement
