Leonardo Boff is a Brazilian theologian and writer widely associated with liberation theology, known for outspoken commentary on poverty, ecology and social justice. Indignado is Portuguese for indignant or outraged, and clips labelled this way circulate online as shorthand for his emphatic, protesting delivery. Like many short voice reactions in Portuguese, it spread through messaging apps and meme edits, where a serious public voice is reused out of context for comic effect. It remains popular because the emotion is unmistakable even for listeners who do not speak Portuguese.
