 Commander Adama has a shaving mirror in his cabin. This mirror is  made by IKEA, and is a model called "Fräck" (spelling according to  IKEA Web site). This word is similar to "frak" (spelling according  to the subtitles with an "a" and without a "c"), which is the  primary vulgarity in the Battlestar Galactica universe. "Fräck" is  Swedish and can actually mean insolent or shameless but the meaning  IKEA is most likely after is striking, which is another  interpretation of the word.
