Dropping Dong is when an actor shows his penis in a film. This is usually considered taboo for American Cinema, and ultimately results in the demise of ones career.
Jeremy: "Dropping Dong is totally acceptable now in movies."
Mike: "It's not Jeremy, it ends actors careers."
Jeremy: "What do you mean?"
Mike: After dropping dong in Wild Things, Kevin Bacon was reduced to doing straight to video and B movies.
This means to snitch on someone or to turn them in. Back when phone calls were only a dime, people would DROP A DIME into the pay phone, possibly anonymously to police. Thus Dropping Dimes got someone arrested or snitched on.
Some one was dropping dimes on me and the police picked me up. I think it was that snitch Jimmy!
