I define a gloryhunter as someone who supports a club solely because they are winning. They do not care how those victories are made, but bask in those successes. When I was little I also liked Bayern, but only because they won everything in Germany at that time. Getting older I realized that and found this a stupid thing to do. That is probably the way many people become "fans" of Bayern.
The worst thing though is the pure arrogance who encounter with those people. The players and the other responsible people at Bayern kind of have the right to be let's say very confident. (Although their current success is bought with money just like in Manchester or Chelsea whose teams are according to Bayerns' people are a shame for football...)
The gloryhunters on the other hand have absolutely nothing to do with any kind of success Bayern has, but still look down on fans of other clubs that do not reach the CL final or any european competition at all. Those guys ruin the clubs reputation more than anything and together with the arrogant public statements from Breitner, Hoeneß, Rummenigge and Sammer make Bayern München so hateble(does this word even exist?
).
Like at every other club there are probably many fans who really love the club and would support it through it's darkest days. But I strongly believe that in Munich this part of fans is much smaller compared to all supporters put together, than at every other club in Germany.
