Dropping fifty means to snitch. To rat out. (2005)
He dropped fifty on his boy and now the cops are after him.

You better make sure that b*tch don't drop fifty on you.

Aslo, since phone calls are no longer a dime, I thought that droppin' fifty made more sense.
In addition, 50 cent is a snitch, so this term makes sense.
