The phrase is a deliberate mishearing of Hurricane Katrina, turning the name of a major storm into tortilla, a flatbread that rhymes only loosely and makes no sense in context. That mismatch is the whole joke, and it spread online as a quotable voice clip shared in meme edits and reaction videos. Users reuse it whenever someone confidently corrects another person with something wrong, or when a clip mentions storms, weather or a similar sounding word, because the line is recognisable even without any original context attached.
