When something bazaar or unusual just happened.
Something you weren't expecting.
When you're at a stop sign and a car on a perpendicular road speeds across, and smashes into something like a school bus.
This one time my dad was checking my sisters car parked in the drive way, Until he hears a rustling sound by his car. at first he thinks it is something in the bushes, but when he stares in that direction he notices his spare tire on the back of his car is moving unusually, and then it pops. He says "What the heck?" and he comes inside to tell me the story later that evening, and I thought to myself WOAH Shoe Hand.
