Sympathetic Spew is an issue.  Around theme parks, it’s a big issue.  Around county fairs, it’s still some sort of issue, but not so much.

At an OutdoorFest, I’m not sure how it’d be classified.  Maybe it depends on how well stomach contents spread throughout a body of baby oil.  If the blending is rapid and far-reaching, I imagine that the retching would also be rapid and far… retching.

Or something.
