Got the Maserati dancing on the bridge, pussy poppin'
Tell the coppers "hahahaha you can't catch 'em, you can't stop 'em"
“Pussy popping” is a dance move where a girl stands on her head or hands, spreads her legs and “pops” her pussy. See this Ludacris video, for example
The last 2 lines evoke an image of Lil Wayne, driving a sick car, accompanied by dancing girls (the car itself is dancing as well?), blowing by / laughing at cops
Or maybe there aren’t girls at all — i.e., “my maserati is "dancing” (i.e., driving fast / recklessly) on the bridge. In fact, I’m being so reckless / show-offy that the specific dance my car is doing is the ‘pussy pop’"
