The 'I'm Mary Poppins, Y'all' meme originates from a pivotal scene in the 2017 Marvel movie Guardians of the Galaxy Vol. 2. While descending from a ship using his Yaka Arrow as a makeshift umbrella, the character Yondu Udonta is told by Peter Quill (Star-Lord) that he looks like Mary Poppins. After Yondu asks if Poppins is 'cool' and receives an affirmative answer, he proudly exclaims the iconic line. The scene quickly became a fan favorite for its mix of humor and sentimentality. In meme culture, the template is used to express pride in an unlikely or eccentric appearance, or to highlight moments where someone is unexpectedly 'cool' despite looking ridiculous.
