the instagator 

usually the instagator perches in the rats nest. where he tries to bwe cocky by beating noobs at chess. the instagator (poo stain) likes to hurt you if you make fun of him. he loves to come in roasty.

When sitting on a skiing chairlift the instagator will bring the bar down with exessive force and yell "comin in roasty"
