6. 'Giggity Giggity!' Family Guy
Giggity Giggity is the ultimate creeper line. Without the context it could be completely innocent and could even be taken as a laughing sound, but as we are so familiar with the situations in which the line is used we understand it definitely is not to be used innocently! Quagmire is a much loved character, albeit sometimes a little gross and wrong but we love him for it. All of the characters from Family Guy are pretty quotable but Giggity Giggity is the definitive catchphrase for this show.
