The line comes from American rapper Fat Joe, who coined 'yesterday's price is not today's price' during a viral interview clip that took off on TikTok and Instagram. Creators seized on it as the perfect caption for rising prices, sold-out drops and personal comebacks, pairing the audio with flexing edits and business wins. Its swagger and quotability kept it circulating as a meme sound long after the interview aired, and it remains a go-to reaction for anyone signalling that their value has gone up.
