Lay terms... please!
I'm not the Doc but as a lifter who couldn't touch the top of his head for a year because he blew out his shoulder in competition, I know a thing or four about rotator cuff injuries.
There are 4 muscles that make up the rotator cuff: supraspinatus, infraspinatus, subscapularis, and teres minor. They basically attach your arm to your shoulder blade in a bizarre and confusing tangle.
The LABRUM is actually the tissue on the inside of the shoulder joint that the ball that forms the head of the upper arm bone (the humerus) fits into. There are also bursa sacks up in there that get inflamed (I had one of those and it hurt. Bad.)
So the Labrum and the Rotator Cuff are kinda separate things but they're very closely inter-related in the way they work with each other. There are strength tests that can usually determine which one of the RC muscles is damaged.
