Also known as a steering wheel spinner, a "wrist breaker" is a device made to attach to a vehicle's steering wheel to give the operator one point of contact with the wheel so it can be rapidly turned. The wrist breaker earned it's slang name through urban myths about people using them in their cars having broke their write when their car's steering violently jerked while going over extreme bumps.

A "Wrist Breaker" is know as a gallon Liquor bottle or Iced Tea jug that has a handle. Such examples are a gallon bottle of Captain Morgan, Jim Beam, Moonshine or a gallon plastic jug of Turner's Tea (Southwestern PA/Pittsburgh area known). While drinking/chugging straight from the bottle/jug will put strain on a wrist thus referencing to a "wrist breaker".
