Popular Kick/Twitch streamer "YourRAGE" popularized this term. Stemming from his expression "OH MY", his stream chat copied his expression and typed it as "O MA". This spelling of the popular expression paved the way for much more nuanced usage of this word. O MA has been used multiple times by streamers and non-streamers alike. Kai Cenat, Agent00, and many others took this expression and therefore their chats adopted this expression. YourRAGE detests this word from becoming mainstream, so not many people know about this word outside of the W/L community on Twitch.
"O MA" can be used in many ways, but mostly used for twists or very surprising events where you would use the word "Oh My!". Due to this very comedic way of saying this common phrase, it is acceptable to even say this in slightly surprising or awe-inspiring events. This would classify it as a "Filler Word" and therefore, slang that can be shaped and molded to whatever the speaker has in mind.

Calling someone this will gain you much street cred. You only call someone you absolutely despise. Like, with a burning passion.
