'Fortalece' is the third-person singular of the Portuguese verb fortalecer, 'to strengthen', and as a standalone meme clip it circulates mainly in Brazilian and Portuguese-speaking corners of TikTok, WhatsApp and short-form edits. The recording's original source is undocumented; it appears to be a user-uploaded voice snippet rather than a line from a film, show or song. Its appeal is the ambiguity: it works as genuine hype, ironic encouragement or a deadpan reaction, which keeps it in rotation across gym clips, gaming highlights and shitpost edits.
