car-breaker
n.— «There is a speed-breaker on the street, right in front of our house. In our neighborhood in Nazimabad, they are commonly called car-breakers because of their size. Rain water was running down the street and the street looked like a river. The river would hump over the speed breaker and fall like a mini Niagara falls.» —“The Window: Celebrating Father’s Day” by Muslim Rizvi All Things Pakistan June 15, 2008.
