Here it goes:

But what about when you are in public and there isn't a bathroom around? Enter the chemical toilet also known as the porta-potty.

I have looked up all the meaning of the word, but still cannot get how someone can enter something.

    It is analogous to voilà in function. It is like a cue for the chemical toilet to come on stage.

  • Either "go into" (a porta-potty is free-standing and has a door) or "introduce", depending on context.

  • Similar to first comment: "the chemical toilet has been invented". But the question needs more context. Jun 4, 2018 at 19:37

    Enter used like that comes from the theater: Enter x stage left, enter y stage right.

  • But why not enters? The porta potty enters is grammatically correct I guess Jun 4, 2018 at 21:47

This comes from stage directions, which were brief - probably because they were originally copied out by hand and people wanted to save effort and paper:

Enter Hamlet

Enter Bob, stage left

It's a direction in a play to say that a character comes onto the stage. It is used idiomatically and metaphorically to talk about something entering the discussion, with the stage being conceptual and metaphorical.
