The line comes from Guardians of the Galaxy Vol. 2, released in 2017, where Yondu Udonta is played by Michael Rooker. In the scene Peter Quill compares his slow descent to Mary Poppins, and Yondu happily embraces the comparison before shouting the line to his crew. The exchange was widely clipped after the film's release and shared as a reaction sound on social media and soundboards. Its mix of Marvel action and an unexpected children's character reference helped it stay popular for entrances, cosplay videos and fan edits.
