I think #KissPeptin wins over ##dickkopf for names

Here is a trial using it https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2800937 with great effect apparently in @mike_johansen favourite journal

#Dickkopf Deutsch hard headed

#KlausFiedler #Dickkopf

Not everybody feels comfortable to comment publicly about #KlausFiedler. Somebody who knows him called him stubborn, which ironically translates to #Dickkopf in German. I think that word describes his behavior pretty well.
