In Colombia it means that it has no strength in his hand, that he drops everything. By extension, let it be mastered or folded. You have no authority, softie. It can be considered synonymous with cowardly, fearful, fearful, pusillanimous, tolerant, condescending. It's the whole opposite of "Iron Hand." Do not confuse with manirroto, which in Colombia means botarate, wasteful. You spend without measure. Although in a certain way you could also say maniflojo (it does not hold anything in the hands).
