Subsequent members of any (but not all) collegiate fraternal organizations who pride themselves on maintaining traditions held close to the collective bro heart. Traditions such as the objectification of all women at all times, the emasculation of any male seen as "un-broworthy", and all forms of drunken depravity such as hazing, vandalism, bare-chested brawling and the veritable crop dusting of nearby sorority house parties with a choking layer of STDs and Axe Body Spray. Such traditions must be carried out and passed on from bro to bro for several consecutive years in order to be a legitimate "bro dynasty".
Discussion of recent bro activity:
"Can you believe those bastards from DTD?"
"I know, every year, without fail, its the same thing, where does DTD find those idiots?"
"I don't know, they truly are a bro dynasty."
