jackknifed
When an 18-wheeler slams on the brakes so fast, the load flies forward like a madman and slams into the truck, making the whole thing look like a wrestling match.
That truck looked like it was fighting its own cargo. It was a total mess.
The load hit the truck so hard it made the whole highway shake.
I swear the truck and the load were arguing. It was like a slap fight on the road.
