A common slang phrase in America used to describe a continuation of thought and expression. Initially replacing the Latin "Et cetera", which turned into "etcetera", which abbreviated to "etc." and no one knew what it meant anymore, it was quickly replaced with the emphatical "blah blah blah".
"I wasn't sleeping right, the breathing strips didn't help, blah blah blah...so I got drunk and took Theraflu and Nyquil."

Blah Blah Blah is another way to say I love you.

Wife: Blah Blah Blah
Husband responds: Ditto

Husband says: I love you
Wife playfully says: Blah, Blah, Blah !
Why does your wife leave you a slip of paper in your lunch that says "Blah Blah Blah" everyday, does she think you talk to much at work? No, that's just her way of saying I love you.
