According to Bud, what was the band's favorite thing to do beside playing music?

At the beginning of Chapter 8, Bud mentions that the band's favorite thing to do besides playing music was to tease each other and talk about Herman E. Calloway behind his back. The band members are constantly joking with one another about their playing abilities and amusing personal backgrounds. When Bud is introduced to one of the band members named Thug, Thug tries to play a joke on him by telling Bud to give Herman a big hug. Bud is street-smart and realizes that Thug is trying to mess with him. The band is also continually making fun of Herman E. Calloway for being heavy, cheap, and mean. None of the band members particularly likes Herman as a person, and they bond over making jokes behind his back.
