Not sure why, but I always find it interesting when shows make up cruse words (more likely to allow characters to swear on TV then for any 'in-universe' reason). I thought this was a good list. Galactica heavy of course. I miss 'felgercarb' from the original show :)

Both BSG and Farscape did a great job of making up Sci-Fi curse words.
