Four bars of lyrics have cost Rick Ross seven figures.

The rapper was dropped from his multi-million dollar shoe deal with Reebok over his apology (or lack thereof) for controversial lyrics that glorified date rape. He's featured on a track by Atlanta rapper Rocko called "U.O.E.N.O", where he rhymes about drugging a woman's drink and taking her home for the night. "Put Molly all in her champagne, she ain't even know it / I took her home and I enjoyed that, she ain't even know it." The company had remained mum for weeks, but finally took a stand after numerous musicians, politicians and women's groups protested.
