🦵 piernas = legs; un piernas is a guy who is all legs and no brain
Literally the plural of pierna (leg). Colloquial Spanish uses un piernas, masculine and unchanged in the plural, for a nobody or fool: someone who merely walks around without a head doing any work. Same pattern as un manitas or un bocazas.
