The phrase seu coração de pedra is a common Portuguese expression for calling someone emotionally cold or incapable of feeling for others, similar to heart of stone in English. Short clips of the line circulate on soundboards and in messaging apps, where users share them as ready made reactions instead of recording their own. Its popularity comes from how instantly recognisable the metaphor is across romantic dramas, arguments and jokes about stubborn people. Because no longer context is needed, the clip keeps being reused for new scenes, edits and conversations.
