What is SAP stands for?

The meaning of SAP is: "Systeme, Anwendungen und Produkte in der Datenverarbeitung'. (in German Language)

It's stands for "Systems, Appilications and Products in Data Processing" in English.

When SAP came to America, it changed to Systems, Applications and Products. In the 1980s it was Systems, Applications and Products in Data Processing, a literal translation of the German wording.

Simple and straight forward answer. Comment me if i'm wrong.
