Well, it could be that Quagmire did something really offensive to Brian's owner, like constantly hitting on Lois in a very vulgar way. Brian, being protective, decides to take matters into his own paws and beats up Quagmire to teach him a lesson.
Perhaps Quagmire insulted Brian's intelligence. Brian is often portrayed as an intelligent dog, and if Quagmire kept making snide remarks about his intellect, Brian might reach a breaking point and lash out at him. In a fanfic, this could be a great source of drama and conflict.
Once upon a time, in a schoolyard, there was a girl named Lily and a boy named Tom. Tom had been teasing Lily for days about her new haircut. One day, Lily had enough. She walked right up to Tom, pushed him hard, and then started punching him on the arm. Tom was so shocked that he didn't even fight back at first. Lily yelled at him, 'Don't you ever make fun of me again!' and then walked away with her head held high.
Not really. In most societies, men are generally perceived as physically stronger, so it goes against the common expectation. However, when it comes to self - defense or extreme emotional situations like the ones I mentioned before, they do happen.
I'm not sure about its popularity. It could be popular among die - hard Glee fans who are interested in exploring different storylines and character interactions. But without specific data on views or readership, it's hard to say for sure.
One story could be in a self - defense situation. For example, a man was harassing a woman on the street, trying to grab her purse and touch her inappropriately. The woman, who had some martial arts training, fought back and beat up the man to protect herself.
In a neighborhood, a girl, Emma, noticed a guy, Ryan, being mean to an old lady. Emma was into martial arts. She stepped in between Ryan and the old lady. Ryan tried to shove Emma aside, but she blocked his move and delivered a series of punches and kicks. Ryan ended up on the ground. Emma's actions made her a hero in the neighborhood and taught Ryan not to be so unkind.
Well, it could be about a scenario where Peter (presumably from some fictional universe) gets into a physical altercation with Flash. Maybe in this fanfiction, Peter has been pushed to his limits by Flash's actions or words, so he decides to beat him up. It could be a way for the author to explore the characters' relationships and emotions in a more extreme way.
I'm not sure specifically as there could be many different versions of such a fanfiction. It might involve Finn standing up to Karofsky due to some form of bullying or conflict that Karofsky has caused in the Glee universe.
One reason could be self - defense. If the boy was harassing or threatening the girl physically, she might fight back to protect herself. For example, if he was trying to force her to do something she didn't want to do.
