Shout to ratchet for backin' out on behalf of my shooter
A reference to the video game Ratchet & Clank, in which Ratchet is known for the guns that he has (similar to “Gunz” if you will).
“Ratchet” is also slang for a firearm, typically a handgun, hence the name of the character. Another piece of evidence that shows that rappers are big video game geeks.
