There are several common scenarios in fanfiction regarding Snape's limping. Sometimes, it's a consequence of his internal struggles. For instance, if he's under a lot of stress from hiding his true loyalties, it might manifest physically, like a limp. Another scenario could be related to his teaching at Hogwarts. Maybe a student accidentally casts a spell on him during a class, and it affects his leg. Or perhaps he's on a journey to find a rare ingredient for a potion, and on the way, he encounters some hostile magical creatures that wound him, leading to his limp.
One common scenario is after a fight with Voldemort or his followers. He might get injured and start limping as a result. Another could be when he's in a hurry to save someone, like Harry Potter perhaps, and in the process he injures his leg.
In some fanfiction, Snape might be limping because of an injury he received during a battle, perhaps with Death Eaters or other dark forces. It could also be due to a lingering effect of a spell gone wrong.
One great Severus Snape limping fanfiction is 'The Limping Professor'. It delves deep into how his limp affects his daily life in Hogwarts. It shows how he copes with the pain and the stares of students, adding a new layer to his complex character.
One common scenario is when Snape is trying to teach at Hogwarts. Sirius might be delusional in thinking that Snape is still up to no good and is secretly influencing students in a bad way, even if Snape is just doing his job as a teacher.
A common trope is the 'Injury Reminder'. In these fanfictions, Snape's limp serves as a constant reminder of a past battle or dark encounter. It adds a sense of mystery and danger to his character.
One common scenario could be that Harry is caught sneaking around the Slytherin common room or stealing potions ingredients from Snape's stores. So, Snape and Draco might make him do extra detention tasks like scrubbing the cauldrons for hours without magic. Another situation could be if Harry is suspected of cheating in a Potions exam. Draco might report it to Snape, and they could punish Harry by making him redo all his Potions experiments from the semester.
Often, Snape will single out Harry in front of the whole class. He might publicly criticize Harry's work or attitude. For example, when Harry is assigned a group project in Potions, Snape might give Harry extra tasks or set higher standards just for him. And during exams, Snape could be extra strict when grading Harry's papers.
Snape could also assign Draco to do research on a particular dark magic item or spell. This would be a punishment as it would involve a lot of time and effort, and also expose Draco to the dangerous side of magic that Snape wants him to be cautious about. It also gives Draco a chance to learn more about the consequences of misusing magic.
One common scenario is that Snape saves Harry's life in a more personal way than in the original story.

And sometimes, it could be a simple moment like when Hermione defends one of Snape's teachings in front of other students, and Snape starts to see her in a new light.
One common scenario is when Snape is in a vulnerable situation, like during a DADA class. His boggart - his father - might appear and start berating him for being a wizard or for being different. This shows Snape's insecurities about his identity.
