When a character is subjected to having one or multiple parts of their body expanded. May lead to hyper situations if they get out of hand.

For when the character's whole body is growing, use body_size_growth instead. Use both that tag and this one if at least one part is growing faster than the rest (e.g. the breasts get bigger the taller they grow).
