In the animated television series The Simpsons, S.N.U.H. stands for Springfieldians for Nonviolence, Understanding, and Helping, although the word itself appears in a number of other contexts in the show.

The mother Marge Simpson creates the group after Homer Simpson gets hit on the head by baby Maggie Simpson. Marge blames the incident on the violent content in the fictional television show Itchy and Scratchy, and starts a campaign to curb violence on television.

The word SNUH appears in a later episode, in a clip from a campy 70s Radioactive Man movie. The word appears, in the typical fashion of superhero movies of this era, in an explosion bubble and accompanied by sound effects.

ZUFF! PAN!! SNUH! BORT! POOO! NEWT! MINT! ZAK!

In another episode, when Marge tries to make Homer promise not to buy Lisa a pony, "snuh" is one of the nonsensical words uttered by Homer instead of making an actual reply.

SNUH in popular usage

Snuh!, as an exclamation, has become somewhat of a rallying cry of Simpsons fans. A student organization at Calvin College focused around The Simpsons has gone so far as to call their organization SNUH, although it stands for Students for Non-ignorance and the Understanding of Hilarity [1]. As a catch phrase, it seems to be related in some way to the futuristic slang used by Amy Wong (for example, "Spluh!") in the animated series Futurama, which happens to be another creation of Matt Groening, creator of The Simpsons.

In the Harry Potter series, Hermione Granger starts a movement to help house-elves, called SPEW - another well-intentioned but largely ignored faction with a not-so-snappy acronym.
