Why is the sweet tooth fairy phenomenon so addictive? Nearly everyone can think them up, for one thing, and you get a satisfying pop of absurdity when one comes together. We all know how illogical and contradictory English can be, but sweet tooth fairies let us turn even the most banal and familiar parts of our language – sweet tooth, tooth fairy – into something strange and wonderful.

A SATISFYING POP OF ABSURDITY

Sweet Tooth Fairies with Braces and Scaffolding that start and finish with the same word. (An original idea flown in by grantbarrett over at wordnik).

Some looping ones, where they can be as long as you like, they have to end on the same word they start with, they can’t have repeats, and you can split one-word compounds into two words (since we usually do it aloud) and even better if they seem to allude to a story.

Posted as the end words of these STFairies. Following them will take you full circle. Hah!

STFairy Rings

This is where all the proper sweet tooth fairy types are. The ones that follow the rules exactly. They are three words where the first and second words form a known expression, and the second and third words form a known expression, and all three words together make a credible expression.
