|1.||on the band shortbus|
Like the more well-known saying, "to be on the bandwagon", but it is used when one likes a band before they become cool.
Steve: "I see a lot of little kids like Green Day these days."
Mark: "Yeah, they're all jumping on the Green Day bandwagon now. But us two, we were on the band shortbus. We got "39/Smooth" when it first came out."
