Truck Off
When two trucks are blocking either end of a road. Neither of them will pull out and are waiting for the other to back down. Sometimes this is accompanied by both truck drivers leaning out the cab and yelling at eachother.
Bob: Why are you late for work Jim?
Jim: Truck off down my road again.
Jim: Truck off down my road again.
