A story that is exceptionally
boring, such as one told by a senile grandfather about that time he got two for one on
onions one day twenty years ago by being the first customer of the day. Just like he did the last nine times he told you about it.
May also be used as an adjective to refer to anything particularly dull.
Boy: Well if you're done with your snory- ...er STORY...
Grandpa: You
don't think much of me do you boy?
Boy: No sir, I do not.
Man 1: What a snory
excuse for a meeting.
Man 2: ...you actually think that was witty
don't you?
