The youngest sister in a family; Baby by name only, usually the brattiest in the line of kin; Daughter with most praise given to her because she is the last girl that will ever pass her mother's birth canal; Known to be Assertive; likes to create her own rules, especially when playing cards or board games; Baby Sister: Nickname given to a younger & dearly loved girl sibling (like: Davina Roxanne) or a brother everyone else in the family thinks is a whiner or a sissy.
When a woman uncontrollably queefs, often on friends. And when everytime a fart is released from this same woman, it smells like baby shits. Thus giving oneself this nickname.
Friend 1:(queefs on friend)
Friend 2: Wtf? Did you just queef?
Friend 1:(lets out a silent fart, but does not say anything)
