muireann is an interesting person who most of the time is a crackhead. she is afraid of unusual things like butterflies but she can be more confident then others when talking to people sometimes. she makes you think she dont cares but sometimes when you talk to her she does. muireann can sometimes show toxic traits and can hurt you alot but when shes a good friend, she is a good friend.

Muireann is a beaut of a person. She can slay both an all natural every day glam (with no effort put in) but when it comes to a night out she will let that hair down and put in some effort. She is annoyingly modest and has no idea of her beauty and therefore never bothers showing it off. A muireann is usually dark blonde hair, has Amazing eyes which would make and guy fall for her instantly. She has freckles which compliment her natural beauty . Muireann is normally and all star she has the looks, likeable character, usually sporty and is also down to chill any time. She is not a relationship type girl as she is the type of person who can't accept that they are pretty and can't imagine a boy fancying her. She is a very good friend, any person with a muireann do not loose her as she is a very important person. Muireanns give the best advice even if they tend to be the most innocent. Don't be fooled even though it may be hard to grasp onto a muireann due to her modesty and the competition with others it's worth it. She has a very attractive body and her ass is massive. She may come off as innocent but once she gets back to your place she is very rewarding. She is the type of girl who would like to do couples yoga and bake together any life with a muireann is a happy and long one. Muireann may come off as judgemental at times. With people she doesn't like she would 2nd guess herself telling them what she thinks. Known for her temper. Tends to be slightly Tom boyish.
