I'm a grown ass man, I don't play with kids
I spray the led, and rip you apart like a Mr. Potato Head
A Mr. Potato Head is a toy for kids, which can be designed in a vary of formations, because the body parts can be ripped off and placed back on… and well, there are a ton of different parts.
Spray the led means to shoot bullets at you. So Cassidy is saying he will shoot you up, and rip you apart. Similarly how one would rip apart a Mr. Potato Head.
Another punchline I was like, Shiiiiitttttttt.
