A fun and very annoying (if said in the right accent) way of saying lollies sweets candy etc. Commonly used to nag parentals and little sisters on long road trips. Always said with an annoying accent
"Bonbons for everyone!"
"Can I has a bonbon mommy?"
"Bonbons for Katelyn! Bonbons! Give her a bonbon Joan! Bonbons! We wants bonbons"
After rolling over and turning around, I was happy to notice Arnold had some delicious looking fudgy bonbons for me to snack on. What a thrilling surprise, and a favorite!
It means you are so sweet like a bon bon! It's a sweet treat! Straight meaning straight up, totally, completely, wholly a bon bon
Person: "...You are one of the most talented girls I know..."
Lisa Cim: "Awwww thank you!!! You are so sweet! Straight bon bon that's what you are!!!!!!!!"
