GSUS is not a word that has synonyms, as it is actually an abbreviation or a slang term that refers to the name Jesus. Some alternative spellings or variations of the name Jesus include Joshua, Yahshua, Yeshua, and Jesús (in Spanish). These names may be used by different cultures, religions, or languages, but they still refer to the same person that is a central figure in Christianity. The name Jesus is also sometimes used as an exclamation or an interjection, like when expressing surprise or excitement, but it is not interchangeable with GSUS or any made-up words.
