Could also mean talkin' smack. Introduced by 50 Cent meaning you are just talking bad about anything or anyone, knowing they either hear you or will find out what you said and possibly retaliate.
used in a sentence: "I heard that bitch was talkin' greasy about me at the club last night, but I bet she won't put her hands on me!"
