What does Bop-type Refrain mean?

Bop-type Refrain meaning in Urban Dictionary

an incredibly esoteric nickname for cocaine. When you look at the initial words on Cole Porter classic showtune "I have a Kick from You", the next verse starts is "Some have a kick from cocaine". Since the years passed, which was altered to "Some just like the bop-type refrain" so children could continue steadily to apply "something Goes" as a high-school musical. People aware of this, wanting to show their particular social refinement and talk about cocaine, all while avoiding eavesdroppers and self-incrimination, replace the technical title of their drug of choice with "Bop-type Refrain" (or simply "Bop-type", although later choice brings with-it a significant chance of dropping your audience.)
