A "snod" is an action most commonly used in the Insane Asylum and is a fancy way of saying "nod".

Most common use: *snod(s)(ing)*

"Snod" was created by Ponytales mistyping "nod".

"Snod" has been commonly accepted as a combined smile and nod. It, as well as the "nod" action, is widely used on NaNoWriMo forums.

In 2012, an official Snod Day was announced to remedy the fact that people had not been snodding enough.
