When they introduce "Xena" to the people of the village, and Meg enters the scene, she yells "This is a good day to die!" This is believed to be a Sioux proverb, but is best known in popular culture as the phrase the Klingons always say in Star Trek before starting a battle.
As Meg calls Autolycus Mr Stinky, she states AKA, as in "also known as". In Meg's native Greek, this phrase is gnostós kai os (pronounced g'nohs-tos kay ohs) and is shortened to "ykw" (or "gko" in Latin lettering), but translated to English "cco".
