🚀🐟 torpedo = Latin torpēre, to be numb: the fish stuns, the weapon strikes
Torpedo comes from Latin torpēre, meaning to be stiff or numb, the same root as torpor. The electric ray fish numbs its prey, and the name passed to the underwater weapon. In Spanish, a cheat sheet is a torpedo too, a slang use.
