Among other things, this word relates to Captain Sensible's political party. He began it as a protest that elected officials do not represent the masses and to give non-voting people an option to vote as a protest rather than avoid voting as a protest.
Disenfranchised Voter #1: I feel really BLAH about all those lying politicans and I don't feel any of them represent me so I'm not voting for any of them.
Disenfranchised Voter #2: I know what you mean--you should consider Captain Sensible's BLAH party.
