A less familiar Scottish adage used for students:
When a student does poorly on an assignment/test/quiz and is frustrated for the long hours devoted to studying. So frustrated, the student feels the urge to murder the/insert into the teacher responsible with a garden gnome.
student 1: SHIT! 45% WTF? I STUDIED FOR THREE HOURS!
student 2: WHY THE HELL ARE YOU YELLING AT ME?
student 1: Sorry, my Gardern Gnome Syndrome (GGS) flaired up.
Instead of raging that you died to a dumb glitch in Fortnite or when you get killed by 72hrs, Tfue or EmadGG, say "GGs Only". Because at the end of the day it's GGs Only.
