This trope was renamed because of rampant misuse. I'm really not sure if this is a valid example or not. Susan is listed under main characters, which makes me dubious that she's really a satellite character. If I'm wrong, feel free to re-add this. (Other possible tropes that might have been meant include Designated Love Interest and The Ditz.)
Speaking words of fandom: let it squee, let it squee.
