According to http://www.cbsnews.com/8301-503544_162-57510587-503544/biden-beer-invitation-no-malarkey-/, here's another quote with Biden using what may be his favorite noun. "He's going to call you, no bull**t," he said. Upon noticing the reporters behind him, the vice president self-edited: "This is no malarkey. You come to the White House. I'll buy you a beer."
malarkey: insincere or foolish talk; meaningless talk, nonsense or foolishness
I found a list of synonyms and related words. I feel many of these "synonyms" describe the feeling I came away with, from the vice presidential debate! I'm still filled with voter's apathy. No clear winner for me, including moderator Martha. I thought Martha was way too tolerant of Joe Biden's constant blurting and interruptions. Having said that, Ryan had his share, considering he even said they should not interrupt each another - just not nearly as many. I was unimpressed and disappointed with the body language from both of them ... especially their facial expressions. Their smart aleck attitudes, smirks and smiles, to me, displayed a lack of serious attitude about this debate. It could have more fit a comedy skit, than a vice presidential debate. Who paid for that shameful display of crap, anyway?

Most everything I've found points to 'malarkey' being of Irish root. For instance 'Sons of Malarkey' is an Irish band. And here is a bit about Biden, and his Irish roots. http://www.huffingtonpost.com/megan-smolenyak-smolenyak/joe-bidens-irish-roots_b_1641678.html ... I also found many restaurants with the word 'malarkey' in their names, also are Irish - mostly taverns and Irish pubs.
