SGDM 

SGDM better known as, ‘Schist! Gods Dammit!’ Is a beautiful abbreviation to express frustration, in the Percy Jackson way.

Percy Jackson fan 1- Dudes! I’m so sick of the cafeteria food, wanna go to the dam snack-bar?
Percy Jackson fan 2- I have to kill some monsters a.k.a homework so this demigod’s no can do on that one.
Percy Jackson fan 1- SGDM! I HATE MRS. DODDS!
