Girl scouts (and girl guides) often have patches to commemorate a fun event. The ones they earn for work go on the front of their vest and have specific criteria for earning them, but are usually more generic in appearance or don't have details about it on the patch.
This type of patch is likely for the youngest age group (4-5) and is meant to be more of a fun patch. I would also guess that the troop is in more of an urban area so there's not much in the way of a very local, small kid friendly hike.
Where do you people live that it would be a monumental achievement to reach the nearest chip stand? Are you in a remote village in the Andean mountains?
... and Tomatoes originated from Central America .... which means that chips and ketchup wouldn't be possible without Native American cultures cultivating these fruits and vegetables
In American, yes, it means promiscuous young woman or prostitute. In Canadian it means irritable or in ice hockey, overly aggressive playing. In British it means fried potato slice selling establishment (stand or shop).
Where in America? I don't doubt it, I'm just not familiar with it. Is it possibly something that has fallen out as a slang term or incredibly regional?
