A chain of logic with ends so remote that to anybody else it seems to be completely unrelated. Like a wiki walk, but through your head, and there's no history.
Example of a non sequitard:
Alice: Hmm... I think Grassy Knoll Dew would be better than Mountain Dew.
<pause>
Bob: Would walruses fight for us in the zombie apocalypse if we gave them buckets?
Bob: Don't even try to figure out how I got there.
1. Latin phrase roughly translating as "doesn't follow" (think: not-in-sequence), i.e. 'non-sequitur' describes something that doesn't follow on from the preceeding information or context. Often used as a form of humour.
A word a phrase uttered during sexy time that has nothing to do with said sexy time with the exception of ruining it.
So this morning my girl and I were all romantic and she gave me one of those realsexy looks followed by a non sexuitur asking about good breakfast places in the 'hood. I hope they were serving sausage because after that I sure as hell wasnt.
(adj) describing a random statement or conclusion that has nothing to do with the statements made prior to it.
Several family members are discussing what to have for supper: "spaghetti? hot dogs?"
when Bill Doe says, "we should hire rodeo camel trainers to help us uncover the secrets of the Bermuda triangle!!"
His statement does not relate to any of the previous statements, and thus is "Non Sequiturious."
