When saying "blah" to someone, means you're not really listening and you don't care what they have to say to you. especially if it's something really important.
For example:
Sally: Did you watch those aliens attack our planet yesterday?
Fred: Blah
Sally: You are a bad pinecone
Sally: Did you watch those aliens attack our planet yesterday?
Fred: Blah

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.
