An exotic form of the "clap" STD that is contracted from sexual encounters with Hannah Montana and/or Miley Cyrus, either at the same time or in quick succession from each other. When both Miley and Hannah are present, the disease is also known as the "boom dee clap dee clap". This can lead to AIDs and/or swine flu, typically followed by death.
"I went to see "Hannah Montana: The Movie" and contracted the boom dee clap."
