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 Dance Crew, Lil Mama was impressed by one of the performances, causing her to exclaim, "That's what I'm talkin' mout!"
