What's the meaning of "bundle of sticks up your butt" in this context?
It's from Gilmore Girls, and Lane has to go to a teenage hay ride though she thinks it's silly.
"I'm still fuzzy on what's fun about sitting in the cold for two hours - *with a bundle of sticks up your butt.*"
I'm not sure about the meaning of the last past of it especially because Urban dictionary says "stick up their butt" describes someone who's unpleasant.
So is she talking about people who go on a hayride? or stick here means hay?
