do this shit for my click like Adam Sandler

He does whatever he does for his click, or group of friends, and since he is a rapper and wants to sound cool, he mentions Adam Sandler who was in a movie called 'Click"
Actually this line is more likely to be in reference of the fact that Adam Sandler is known for putting his closest friends in his movies. So Wayne's saying he's always looking out for his clique like Adam Sandler does.
in addition to creating supporting roles for his friends, Adam Sandler also starred in a film called "Click"
