It's a cast shadow.
Cast shadows are designed to show a lower level of a pseudo light angle, thus creating longer shadows. Drop shadows are designed to show a high level of pseudo light resulting in a small offset shadow.
I don't consider this to be a new kind of shadow. I think it is still called a "drop shadow".
Also i agree with the comments. Imo this is not a shadow in your picture, it's a motion blur, eventhough it should be white.
