Well, everything is possible! Should be the task of the profilers. As a native speaking german i can assure everybody, that using the term "Wahnsinnderholger" is result of admiration. It's like "great guy that Holger". German use that phrase a lot in relation to big impressions. Like taking a look at the grand canyon or the empire state building. We do like to say "wahnsinn!". But who knows?!
