And if you are my rival, then that means you're suicidal
Going against Nicki is like killing yourself.
To be clear, this means that opposing Nicki, a rap superstar of her own right, is equivalent to professional suicide. When other rappers try to top Nicki, their careers will flop (die/be killed). This is not to be taken literally to mean that the artist wants to kill her/himself.
If you make yourself her rival (or cross her in any way), she’s going to murder your career. There’s no hope of surviving a feud with Nicki Minaj, so tread lightly.
