One of those girls who has a girl crush on another girl, and who becomes a close
friend. They then begin to copy said
friend's every move, and change thier appearance to resemble them. The goal of the body snatcher is to become the other girl entirely. Warning signs that a
friend is in fact a body snatcher: clinginess, an adoption of
one's own personal method of speech, multiple calls from said person, clothing missing from one's closet, the disappearance of one's toenail clippings, and waking up one morning, with the odd sensation that someone has been in the room, to find a chunk of one's hair missing.
"Do you see that girl who follows Stephanie around all the time?"
"Yea, she says Stephanie is her best
friend. She dyed her
hair to match her yesterday."
"I know, she is a body snatcher if I ever saw
one."
