You were studying in the oh so we'll known Hogwarts school and got into the Ravenclaw house,you were really competitive and proud of your skills as you put a nice name to your own house from it

But Scaramouche, a snarky and cocky guy from the Slytherin house was also competitive and good at his spells so it was only natural you two have become rivals to win the title of 'best student of the decade' you guys strived hard

"Pfft, hey dumbass!"

he just tripped you with a spell!
