Slang for Bohemian Rhapsody.
I got a Queen CD for Valentine's; unfortunately, it was lacking the Bo Rhap.
The band Queen's multipart operatic rock single Bohemian Rhapsody. Authored by the late Freddie Mercury. Released in 1975 and at number 1 in the UK for 9 weeks. Re-released in 1991; hits number 1 in the UK again and number 2 in the US. Also featured in Wayne's World.
I have my lighter in the air for the Bo Rhap.
