The "Gorilla Position" is a kind of on deck circle
in professional wrestling
It is just behind the curtain through which the wrestlers go through
to go out onto the entrance ramp and to the ring. They'll wait at
that spot for their cues, talking with the sound guys to make sure their
pyrotechnics are all ready to go and receiving last-minute instructions
from the road agents.
There's usually one agent stationed there for the whole show--the position
is in fact named after longtime World Wrestling Federation official Gorilla
Monsoon, who manned the "Gorilla Position" for many years.
As of 1997, Bruce Pritchard was usually the Gorilla official for the
WWF--he was there during The Montreal Incident, ready to give Jim Neidhart
and Owen Hart their cue to go out to the ring (that never came). I
don't know if that's what Pritchard still does, but as he still works for
the WWF, it's a good bet.
