GSC

Stands for "Group Shitting Club" and refers to a collective of male highschool students (most likely European) who time their visits to the school bathroom in order to consume contraband and most prevalently use the bathroom devoid of any privacy.

Students not affiliated may see members of a GSC takings shits with stall doors wide open, two or more guys pissing in the same urinal, or GSC members watching as another member takes a shit.
Adam: "Dude, I walked in on Sam in the bathroom, he stared at me while taking a shit with a bathroom stall wide open"

Reed: "I see you saw the GSC, try outs are tomorrow" (muffled laughing)
