Here's why:
* "Je suis" means "I am" in French.
* "Malim" is not a French word. It might be a misspelling of "malin," which means "cunning" or "sly."
* "Comme" means "like" in French.
* "Um" is an English interjection with no meaning in French.
It's possible that this phrase is a made-up expression, a deliberate misspelling, or a result of a language learning mistake.
To get a meaningful translation, you need to clarify what the intended meaning of this phrase is.
