I blast the tech at your dome to leave you restin alone
Tech is short for Tech Nine, which is machine gun pistol.
Dome is thug slang for head.
Resting is another word for dead, which comes from the word sleep. Putting someone to sleep means to kill them. Before dumping someone into the sea to drown, some say the phrase “Sleep with the fishes” as apposed to “Swim with the fishes”.
