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 deeclap."
This movie was written and produced by the decent Dee Snider of Twisted Sister fame. This movie really sucks, but each time you see it on, you want to see it. Captain Howdy and Charleston Hendricks are the lame names he came up with. But what can I say, it's a funny movie.
Hey, have you seen Dee Snider's Strangeland on Showtime? It really is an enjoyable flick, although out right dumb at the same time. I'm out like a hurricane, so latas.
A reference to the african american actor Billy Dee Williams and his cool calm,demeanor. You may know him from such movies as Mahagony, Batman,Forty commercials, Undercover Brother and the Ladies Man. Keeping it Billy Dee is the act of staying cool and calm, especially in relation to women.
Dan- "I dunno dog I'm really worried about this date"
Ryan-"Listen homie, just keep it Billy Dee and you'll be ballin this girl in no time."
