Definitely not. This kind of teasing is not only unethical but may also have a negative impact on the relationship between boys and girls. It violates the basic principle of respecting others and can lead to an unfriendly or even hostile atmosphere.
No, it is completely inappropriate. Preteen girls are minors and spreading any stories that could be misconstrued or violate their privacy and dignity is unethical.
From a moral point of view, this kind of teasing is unacceptable. We should promote healthy and respectful interactions between boys and girls. Teasing in this way can make the other person feel uncomfortable and harassed, and it also goes against the values of modesty and respect in society.
Educate people, especially the youth, about the importance of positive values. Let them understand that creating or spreading such stories can have a negative impact on others and the social environment. For example, in schools, teachers can include relevant moral education in the curriculum.
I'm not sure specifically which 'little bad legs story' you are referring to. It could be a story about a character with some issues related to their legs, perhaps a little animal or a person who has some misadventures because of their legs.
