Hype man


A hype man in hip hop music and rapping is a backup rapper and/or singer who supports the primary rappers with exclamations and interjections, and who attempts to increase the audience's excitement with call-and-response chants.
Music writer Mickey Hess expands the term as follows: "a hype man is a figure who plays a central but supporting role within a group, making his own interventions, generally aimed at hyping up the crowd while also drawing attention to the words of the MC".
