The moment comes from Harry Potter and the Philosopher's Stone, the first Harry Potter film, released in 2001, during a Charms lesson where first-year students practise the levitation charm.

Clipped and shared online, it is now used far beyond Potter fandom as shorthand for getting a familiar phrase slightly wrong, especially when confidence outruns accuracy.
