What's in a name? that which we call a rose

By any other name would smell as sweet;

So Romeo would, were he not Romeo call'd…'

She's basically saying that a rose is still a rose even if it were called nobbin or boppin or something. It would still smell the same; it would still be the same thing. So, her point is that if Romeo were called Ben, he'd still be the same awesome guy and then she could date him.
