Nothing in my mother's kitchen,
Stomach sounds like the clouds ignited and the thunder hitting
So the well-screwed kid ended up with more than a couple missing

from Joe Budden (Ft. Crooked I, Joell Ortiz & Kaydence) – Skeletons Lyrics on Rap Genius

Meaning

Joell’s mom was too poor to buy food so he had nothing to eat as a kid. His hunger was so ferocious he reminisce his stomach growls sounding like thunder

Living in poverty, he had no choice but to rob others kids' lunch to eat.

This also explains the next metaphor about screws. He feels that the environment in which he grew up kind or screwed his life up in a way. The aftermath has left him with more than a couple screws missing (loose). The hunger made him go crazy.
