Short irish girl usually pretty with massive tits. Very shy gal, and is awkward around people she doesn't know, but once you get to know her she doesn't keep her mouth shut. Tends to ramble and has a fucked up way of showing affection. Everyone who meets a beibhin instantly thinks shes very innocent on the inside but is anything but, she turns into an alcholic at parties and gets a tad bit slutty. Is sometimes bipolar meaning she gets very hyped up but then suddenly is miserable and brings down the whole mood of the room. Never cross a beibhin for she holds grudges.
