Immediately, some others in the group joined in with their appraisals; pretty well in agreement with the first comment. This confused our girl, who was totally clueless as to how they derived their conclusions.
So, in total naiveity, she asked. And got several plausible reasons.
1. The other girl had outsized breasts that seemed larger in proportion to her slim body;
2. She was wearing form-fitting clothes;
3. Her breasts were "too perfect:" they were cantaloupe-shaped rather than pear-shaped.
4. They were positioned relatively high on her chest.
Melinda then queried, "Why don't you ask her if they're real or store-bought?" And immediately became aware of the fallacy of that approach.
Later on, while back in the bunkhouse, Cowgirl Melinda decided to test that hypothesis. Taking off her denim jacket and Western shirt, she donned a baby tee. And checked herself over.
"Those bitches don't know what they're talking about," Melinda exclaimed!"
Smitty, who happened in at that moment, asked, "What bitches?"
"Oh, just the usual loudmouthed variety."
"You must have been in Ten Sleep today, Melinda."
*My substitution for the dysphemism that was actually used, which Cowgirl Melinda would never use.
