throwout bearing

Da twisty-turny hinge-thingy dat lets da dumpster-flap or trash-can lid open and close.

Due to so many of da modern vehicles' having automatic transmissions, fewer clutches have to be replaced nowadays, and so da metal-recycling bin in a typical neighborhood garage seldom gets opened to toss in worn-out manual-engagement-mechanism bits; said receptacle's throwout bearing therefore gets less of a workout.
