Blueberries

[Julene]

To come up with a complete non-sequitor in a conversation. The [entymology] of this word began on The Geek Show Podcast when panelist Leigh George [Kade] would be accused of completely [derailing] conversations with completely irrelevant information. One day, when he wasnt there, a fellow panelist decided to fill in for him and shouted Blueberries! for no reason.
Its caught on with the audience of the show and is a recurring declaration when an irrelevant, derailing comment is made.
