Pre-Gig Shit.
Basically, before a performance of some kind -
music, drama, dance, martial arts,
whatever - You go have a shit. Why? to get rid of excess weight and so you don't shit yourself on stage pretty much.
A PGS is considered a social event and many PGS-ers can go together to engage in humerous banter and to describe the size, shape and consistancy of the shit. You have to be
pretty open and easygoing to be a true PGS-er.
"Who's coming for a PGS?"
*most of the cast troop off to the bogs*
"omg i think i split myself!"
"

blood?!"
"oooh, thats a sloppy
one, tonights gunna be a good show :D"
