Rumors has it, that Messy Marv was TLC's 'hook up' when they came out. So when they dropped ``No Scrubs`` he felt offened and made the diss track on his 1999 album called ``Hoe's Ain't Shit´´. Plus since it was way later in their carrer another factor for the track was that they acted like they didnt know him at an award show.
