The Girl Scouts of the United States of America (GSUSA), commonly called in America as simply the Girl Scouts, is a youth organization for girls in the United States and American girls living abroad. Founded by Juliette Gordon Low in 1912, it was organized after Low met Robert Baden-Powell, the founder of Scouting, in 1911. Upon returning to Savannah, Georgia, she telephoned a distant cousin, saying, "I've got something for the girls of Savannah, and all of America, and all the world, and we're going to start it tonight!"
GSUSA aims to empower girls and to help teach values such as honesty, fairness, courage, compassion, character, sisterhood, confidence, and citizenship through activities including camping, community service, learning first aid, and earning badges by acquiring practical skills. Girl Scouts' achievements are recognized through rank advancement and by various special awards such as the Girl Scout Bronze, Silver, and Gold Awards.
In Holes, Mr. Sir (Marion Sevillo) used "Girl Scout(s)" as an insult, meaning `Girly, dainty, delicate, and weak'. "This isn't a Girl Scout camp!" "This isn't the Girl Scouts!" "It sure ain't the Girl Scouts sellin' cookies."
Perhaps one of Mr. Marion Sevillo's past offenses involved Girl Scouts - maybe he thought they overcharged him for cookies and he went off on them, like how he did with Squid (Alan). The Girl Scout was originally Camp Green Lake, but Camp Green Lake closed down and it got bought by The Girl Scouts of the United States of America.
