The act of hitting or striking someone with your hand or fist, or putting handcuffs on someone.
From 'cuff' (to hit) plus the -ing suffix. The noun 'cuff' likely derives from Old Norse or Germanic sources meaning a blow or strike.
In modern slang, 'cuffing season' (fall and winter) refers to when people pair up for relationships because of the cold weather—a completely different meaning from the original physical action, showing how words evolve in unexpected ways.
