Darren Robinson (June 10, 1967 – December 10, 1995), also known as Big Buff, Buff Love, Buffy, The Human Beat Box, The Ox That Rocks, and DJ Doctor Nice (among other aliases), was a rapper, beatboxer, and actor who was a member of the 1980s hip hop group The Fat Boys.

The film, loosely based on the early days of the Def Jam record label, also featured Blair Underwood as Russell Simmons (named Russell Walker in the movie), and record producer Rick Rubin, along with Run DMC, Sheila E., Beastie Boys, Kurtis Blow, and a young LL Cool J.

In December 1990, as the group’s fame was declining, Robinson was charged with filming a 14-year-old girl being sexually abused during a party, four months prior, in suburban Philadelphia.

[2] Robinson pleaded guilty to sexual abuse of children, and was sentenced to two years' probation and fined $10,000.

He had been diagnosed with lymphedema, or fluid buildup,[5] and died of a heart attack on December 10, 1995, weighing 450 pounds (200 kg).
