The 'That's That Me Espresso' meme stems from the catchy hook of Sabrina Carpenter’s 2024 hit single, 'Espresso.' The lyric 'That’s that me espresso' quickly became a viral sensation on platforms like TikTok and X (Twitter), symbolizing a person's intoxicating or addictive effect on someone else. Users often pair the text with images of themselves looking stylish, celebrities acting confident, or humorous situations where they are the source of someone else's obsession or insomnia. It represents a playful boast of self-confidence and has evolved from a simple song lyric into a go-to caption for showing off your 'it' factor and 'main character' energy.
