March Baby
North american term for a person who exhibits shady and especially toxic traits that painfully complicate your life and/or someone else's. This type of behavior can last from minutes to months(so be careful), coming in at random times or even periodically. Though there's one thing you can certainly expect when associating with a march baby, which is emotional distress, so brace yourself.
She's such a March Baby, isn't it obvious? I lose brain cells every time i see her.
