LORELAI: [sighs] This man knows all my secrets. All of my bad girl moments happened with him – my worst fashion choices, my big hair days, the wearing of the Bonne Bell Lip Smackers around my neck – it was all with Christopher.
Bonne Belle Lip Smackers are flavoured lip balms. They were first introduced in 1973 by the Bonne Bell cosmetics company, and aimed squarely at the tweens and young teens market. During the 1970s and ’80s (when Lorelai was a child and teenager) it was fashionable for girls to wear large-sized Bonne Belle Lip Smackers on strings around their necks.
