An alternate spelling of feldergarb. A euphemism for "crap" in the Colonial vernacular; also used to mean garbage or nonsense. This word originated in the Science Fiction series Battlestar Galactica (1978) and was one of the expletives created to get swearing past the censors.

lil mad is like big mad but the opposite, you mad but not mad to the extent of pullin somthin

Felgercarb! A space aged swearword, originally from Balltestar Galactica back in the 70's. I've been saying it since about 1980. I bet we hear it in the new Battlestar Galactica movie.
