I agree with Mother Jones: Linger, an "internal feminine flavoring" mint—an Altoid for your twat—sounds like a terrible product. Linger mints are merely repacked breath mints that come in an ugly tin with a jacked-up price. MJ:

A little digging revealed that Linger is made/distributed by a company called Admints, which just happens to make trade show mints. And the Linger samples just happen to have have the exact same shape, taste, and ingredients as Admint's sample mints.... And if you actually do expect to use Linger to "flavor the woman in a manner that is safe and effective," be warned: its primary ingredient is sugar, which is not safe for the vagina. It messes up the pH and can lead to a really painful yeast infection, a condition that definitely doesn't make someone want to "linger."

However... I don't think the "Linger" concept can be dismissed as some sort of anti-vag, anti-lady-bits plot. A lot flavored condoms and flavored lubes and chocolate-flavored sex lotions are sold to women who think dick tastes nasty and can't be bothered to acquire a taste for the unadulterated dick. It seems only fair that some sort of twat-flavoring product—vag-safe, of course—come to market for straight guys and the odd—very odd—lesbian who can't be bothered to acquire a taste for unadulterated lady bits.
