Susie's Mom is Susie's Mother. She was seen in one strip from the waist down (looking like Calvin's mother from the waist-down). And she was referenced by Susie in another. Her mother appears when Susie goes to Calvin's house to ask for eggs for what looks like a tea party and she asks if they gave her eggs, but Susie, meeting Stupendous Man, said no one was home. And in yet another she called Calvin's Mom because Calvin dropped a snowball on her head from the top of a tree as Stupendous Man. She appeared when Calvin was trying to smash Susie with a giant snowball. When he is caught, he quickly says he is selling the snowballs.
