It's bad enough that rapper Waka Flocka is feeling himself and there's NOT MUCH to look at, but to take shots at Oprah Winfrey (the woman who can make or break someone's career) is another thing.

In a video footage obtained by RadarOnline, the 27-year-old Atlanta based rapper was videoed making some disgusting and cruel slurs in a shocking diss at Winfrey, 59.

RadarOnline reports:

The sickening cell phone video was shot up to three years ago at a downtown Chicago hotel at McCormick Place, the hometown of the billionaire media icon.

On the tape, the obscene rapper — along with members of his entourage – make a series of swipes at Winfrey.

“She’s got a million dollar p*ssy,” one individual said in the 22-second clip, which you can watch below.

Waka — aka Juaquin Malphurs – then responded with the offensive low blow: “I won’t f**k that ugly b*tch!”

But a pal of Waka’s appeared to feel differently, suggesting: “I’ll f**k the sh*t outta Oprah! I’ll get her pregnant!”

“Waka and some of his crew members were having a random conversation about what celebrities they would like to have sex with and Oprah came up,” a source who was inside the room explained to Radar.

“The whole conversation was inappropriate.”

Waka has not yet commented on the tape.
