When thunder comes it rains cats and dogs
When gunshots are fired (or the metaphorical thunder), cats and dogs, or his friends, die. It’s a reference to the old saying “It’s raining cats and dogs”, and also demonstrates some wordplay as the TV series ‘ThunderCats’ aired during Kendrick’s youth.
It’s also a metaphor of the saying, “when it rains it pours” (meaning that trouble for dave’s brother just seems to exponentially grow and never get better).
