Heard about some guys killed inside my old junior high's field
They said a crackhead did it for white powder
He fiending and so he left 'em leaning, I seen 'em
To just a day ago, that's the way it go
Where they ain't paying dough, so get to laying low

from Elzhi (Ft. Fes Roc) – The Science Lyrics on Rap Genius

Meaning

El recalls the story of a few people murdered in a stick-up gone wrong
When the addict found that they were either unwilling to give or had nothing valuable to give he tied up loose ends

This brings further evidence that nowhere in the streets are safe if people are being killed in High School football fields over drugs with no discretion

El then ends the verse with some nice wordplay,

If you don’t have any dough (money) you should lay low (be cautious and avoid others) or you will be laying low (dead)
