Blah

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

'Blah' is a replacement word for 'bro' or 'brother'. It is often used when the speaker is not bothered to pronounce the listeners name. 'Blah' is often used after the word 'chyeah' to emphasis excitement or reinforce the speaker and listeners understanding.
Speaker 1: "hey dizzle, you enjoy the party last night"
Speaker 2: "yer it was pretty sweet, did you end up taking the chick back to yours?"
Speaker 1: "chyeah blah"

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.
