"I got a bad habit,/And it ain't goin' away." -The Offspring, 'Bad Habit'

Gallus is known for his habit of using....certain language that shouldn't be used in school. Headmare Starlight Glimmer has offered a solution to help with this problem: a swear jar. But for some reason, she insists that I help by being in charge of the jar. What in Celestia's name did I do to deserve this?
