|Düd•dé•brol•-ogy|: The Sub-field of Archaeology concerned with the study of Dude Bros. Often involves extensive field research (i.e Frat parties, The Club, Universities, etc.).
There are many 'bro' cultures that Dudebrology is concerned with. Some examples are skater-bros, velo-bros, sustainabilibros, etc.
What's Marcus doing at that tailgating party? Oh, he's not there to party, he studies Dudebrology.
