A boxer weighing at most 112 pounds (51 kg), the lightest weight class in professional boxing; also means something very light.
Compound of 'fly' (suggesting lightness and quickness) and 'weight,' a boxing term created in the 19th century for the lightest boxers.
Despite being the lightest boxers, flyweights can be incredibly fast and skilled—Manny Pacquiao started his legendary career as a flyweight, proving that smaller doesn't mean less powerful!
