Brennan 

A skittish, awkward man who is frequently picked on for his attributes. Brennan(s) typically show qualities of extreme gluttony, and negligence for body care (Which leads to extreme odors, hair growth, etc) While Brennan's try their best at all activities, they always fall flat and fail to accomplish anything and refuse to give their effort to become better. They can typically be accompanied with extreme libertarian views, and are generally bad human beings to be around.

Brennan 

A Brennan is a sarcastic, logical, and loyal and usually hangs out with guys. She likes to prank people and gets into detention a lot for stupid things, like talking in class, but doesn't really get caught for bad things. Her friends are usually very protective of her and a Brennan has a good sense of who is a friend and who is a foe. This can take trail and error, but a Brennan is smart and resourceful. She doesn't like to ask out guys or admit she likes them because she is very proud. She usually has the mind set of, "What can't I do?"

Boy: I would ask that girl out but she looks terrifying
Friends: Oh, that's just Brennan!
