Number 8: never keep no weight on you!
Them cats that squeeze your guns can hold jums too

from The Notorious B.I.G. – Ten Crack Commandments Lyrics on Rap Genius

Meaning

Don’t keep a large quantity (“weight”) of crack on you. Let your gun-squeezing underlings bear the burden of liability if you get caught

“Jums” are jumbo crack rocks (usually sold for $20); don’t sell these yourself! Hire somebody (helps you, helps the economy)
