Does God care if we make fun of him?

Because my cousin always makes fun of God and challenges God to come down and fade or fight him for people who don't know what that means but yeah God never shows up. Then my cousin was like ok if I make this shot from half court God is yellow like a coward and he made it all net. Plus think about it, my cousin says god might be like the genie on aladin with like all the power but itty bitty living space. Maybe we have to stop praying for ourselves and make our last prayer to free God from his job. Because I think God likes my cousin because he is good at everything and he's super fast and he can do 40 pull-ups and he is already on 13u and he's only 10 and all the girls like him even 6th graders even one 8th grader but she's a pedophile that means but yeah I never make fun of God yet he doesnt hook me up why?
