A guy between the age of 17 and 23, typically found at a university, who has all the usual attributes of a bro, but who's overall appearance including hygiene, hair style, and sometimes even facial structure, closely resembles that of a rodent.
Dude, Chad hasn't shaved or showered since the Dave concert and his hair looks like a mangy beaver. He's really turning into a brodent.
