Midna says

Midna is your sidekick in The Legend of Zelda: Twilight Princess, and unlike many charecters in the series, she has spoken dialouge. This would be a good thing, if not for the fact that every bit of dialouge is incoherent jibberish (She mostly communicates to Link via text boxes). However, as soon as her nonsense-language hit the internet, fans have interpreted it into whatever random, and often disturbing, sentences they can think of. Hilarity ensues.
