The garage girl might be working on her car when she starts to feel a presence. She ignores it at first, but then things start to move on their own. The 'gets banged' part could be when an unseen force slams her against the wall of the garage. This is just the start of the horror. As the story progresses, she realizes that there's an ancient curse on the garage, and she has to find a way to break it before the entity completely takes over her or kills her. There could be all sorts of spooky elements like cold spots, strange whispers, and objects moving by themselves.
We could start by making the girl a strong - willed character. Instead of being a victim, she could be a mechanic in the garage who is constantly underestimated by the male gang. But she uses her skills and intelligence to outwit them and prove that she is more than capable in a male - dominated environment like a garage.
Well, it could be that the 'garage girl' is a mechanic who discovers some strange things while working in the garage. Maybe she stumbles upon a hidden compartment in a car she's fixing, and as she tries to figure out what it is, she gets 'banged' in the sense of being hit on the head and knocked unconscious. Then the mystery unfolds as she tries to remember what happened before the incident and what was in that hidden compartment.
Perhaps the moral could be about the power of bystander intervention. In a rewritten version, if some of the characters in the 'gang' realize that what they are about to do is wrong and stop it, it teaches that people should not be silent when they see something unjust or harmful happening. It encourages everyone to be an upstander rather than a bystander.
If we consider this without sexual connotations, 'garage girl' could be a girl who has a particular interest in the garage area. 'Gets banged' can be seen as an accidental impact on something related to her garage activities. The 'clothing budget' part comes in because, for example, she might have planned to use that money for new clothes, but now she has to reallocate it to deal with the damage in the garage. Maybe she was going to buy a new dress but now has to use the money to fix a broken shelf in the garage that holds her tools.
Once upon a time, there was a girl who loved to spend time in the garage. She was always tinkering with old bikes and fixing up things. One day, while she was trying to move a big box of spare parts, it accidentally tipped over and banged into her little toolbox. Some of her tools got damaged. Now, she had a clothing budget that she was saving up for a new school uniform. But she realized she had to use some of that money to buy new tools to replace the damaged ones. So, the garage incident had an impact on her clothing budget.
