Sean Paul?

i didnt understand one line in the lyrics of his famous song "get busy" whould u please help me?here itis:

Yo sexy ladies want par with us
In a the car with us
Them nah war with us
In a the club them want flex with us
To get next to us
Them cah vex with us
what does""Them nah war with us"""mean?

It means "They don’t fight with us"

nah = no
war = fight
