One, usually a young girl, who is kind and cute but has a mean side and evil streak. Thus, when somebody so potentially cute acts maliciously, they are excused as being a little "sweet heart in training" or a little "S.H.I.T."
Please forgive my Sweet Heart In Training for drowning your cat. We are working on her manners, the little S.H.I.T.
