A phrase similar to talking about. Used by certain celebrities who are convinced that they know what they're talkin' mout, but really don't know what they're talkin' mout.
On that last episode of America's Best DanceCrew, Lil Mama was impressed by one of the performances, causing her to exclaim, "That's what I'm talkin' mout!"
When some nigga all up in your shit, cockblockin or whatevever actin like he knows you personally. But he really is all up in the kool-aid and dont even know the flava. So basically a fake ass nigga who thinks he knows some shit, but in reality that nigga is straight retarded.
Man tell your girlfriend to quit "talkin that yin-yang" on me, its not my fault i got that trick pregnant, im trying to get my dick wet tonight, and she cockblockin like that shit was her job. That girl is a lil cunt baby bitch...
