A total pervert who no one cares about. Also a total idiot. May seem hot or sexy but he'll break your heart in one second. Brennan is a awful person.

Get the Brennanmug. Brennan is a young spirited girl with a kind heart and an adventurous mind. She tends to be quite the party girl and loves hanging out with friends. She is energetic and cant sit still. She’s optimistic, and has this bright personality everyone wants to be around. She loves to laugh and be silly. She always wants everyone to be happy and accept her. She always looks on the bright side of things and tries to stay positive, which can sometimes get annoying, but she never means to be. Brennan has a gorgeous body and personality, and is quite humble too. She can tend to be quite the freak, and is known to be good in bed. Although she is very kind, whenever somebody threatens her friends or family, she won’t hesitate to stand up and get feisty. She has bright blue eyes that you can get lost in, and if you ever meet a Brennan you will fall in love. All the guys want to have her, and all the girls want to be her.

Get the Brennanmug. 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.
