present participle. Blah-blah-blabbering with a side of yada.
Real citation: "We know the interwebnetthing is bad, all right? It's bad for us and it's bad for kids. We encounter all manner of weirdos, psychos, perverts, freaks and assbananas. But enough about my blogroll! I know my kids are online and I'm fine with it. They have their profiles set to 'private' now (meaning they have to add you as a 'friend' before you can see their info and pics). They know not to put their last names and addresses out there. They're not going to run off in the middle of the night and meet John Mark Karr (they're too old for him anyway). Blah blah. But the schools are totally consumed with yap-yap-yappering about Myspace as if Satan himself runs the damn thing."

Made-up citation: "Cease thy yap-yap-yappering! Such prattle-boxing is offensive to Odin above, molemen below, and even woodland critters, who are usually a forgiving audience."
