Jesus handle: (jē'-zŭs hăn'-dəl) n.
1. The grab bar or handle in a vehicle that you instinctively lunge for as the driver causes it to pull G's around a corner. So named for the involuntary exclamation of "Jesus!" as you do so. "I hate riding in the mountains in your car; it doesn't have a Jesus handle on the passenger's side."
