One reader protested: "Oh dear! When we played stinky pinky, we always required that the number of syllables in the pair match. So, the answer would be a stink pink, a stinky pinky, a stinkity pinkity, or the like. We like the stricter rules better—seems tidier somehow."

Another recalled: "We called them "inky pinkies" (probably because my mother considered stinky a "four letter word"). A one-syllable pair was called an "ink pink." Two syllables constituted an "inky pinkie." Three syllables: "ink-inky pink-pinkie." And the crowning glory, four syllables, was "ink-inkedy pink-pinkedy." I don't think we ever got beyond four syllables, but we certainly tried!!"

Other variants were "Hink Pink," "Hinky Pinky," "Hinkity Pinkity," and "gestinkety-gepinkety."

And four syllables (it can be done):

Not quite rhyming but irresistible:
