There is no real meaning for those words. In Japonese, Speak short and in the mark is considered rude, so they add somo words thats sound pretty or at least aggressive?
For exemplo, to speak in a formal way you need just add "desu" in the end of your sentence. "Desu" is abreviation for "Degozaimasu,", "Degozaru"
Just think it like "dattebayo" from Naruto
