We gotta fight, fight, fight, fight, fight for this love
We gotta fight, fight, fight, fight, fight for this love
We gotta fight, fight, fight, fight, fight for this love
If it's' worth having, it's worth fighting for oh-oh-oh
It is basically saying that love is something that you have to earn it doesn't just come so you have to fight for it to gain it if not then no love your way.
