Dickkopf piranha!???

I think the jerks who sold you the P's where making some mucky on you man. Kopft means "head" in german, so now you know what is Dick kopft.....

Regarding P's ID, I would go with RBP as well.
Don't buy more fish from those punks, they are making fun of you and the clients must not be the object of some jerk salesclerk jibe.
Cheers.
