Another troll trying to get reactions while posting something he himself does not believe in.
"Muger" is just combining "Mug" (as in Mug if the Month) with "Roger". He likes to exaggerate to the maximum possible extent, it seems. But when it becomes simply too much to be believable there is no point in repying.
ah...i was forgetting...i don't know also frauderer - ERER is clear, but frau??? what means??
