(TMZ) - Rapper Young Jeezy was just busted by cops outside Atlanta -- and booked for obstructing police officers ... TMZ has learned.

Law enforcement sources tell TMZ Jeezy -- aka Jay Wayne Jenkins -- was arrested in Alpharetta ... after cops responded to an alarm call at his girlfriend's home ... it's unclear who or what triggered the alarm.

When cops arrived on scene ... TMZ reports Jeezy was uncooperative with officers, refusing to identify himself, and cussing them out.

According to TMZ, Jeezy told the officer who asked for his name and ID, "F**k you, I ain't telling you" -- and he attempted to pull away when cops were slapping the cuffs on him. 

As TMZ reported ... Jeezy was arrested earlier this month for battery, false imprisonment and making terroristic threats after a blowout fight with his son.

He's been booked at Fulton County Jail.
