A person who is a load to others; always brings problems, is a hassle, is heavy, and has no value (good for nothing).
My mother in law is a Sandbag, because she doesn't bring any value to her own marriage and ours. She doesn't work, just watches TV, complains all day, manipulates and wants to divide. Only represents some kind of problem no matter what, brings nothing valuable to society.
