Of course the Greek is "skata," George. Duh. (I mean, I already knew Greek root of words such as "scatalogical," but I forgot.) Thanks for the memory refresher.

"Scheisse" is the noun, but isn't "scheit" the 3rd person singular present tense of the verb "to shit" in German?
If it isn't, I've been getting embarrassed unnecessarily when I make a slip of the tongue while singing "O Tannenbaum" and sing "... nein, auch im Winter wenn es scheidt" instead of "... wenn es schneit."
