The "summoning ritual" in question requires the participant (in this case, Evan) to dress in "traditional garb" and wear an "exotic headdress". They have to substitute a dashiki and a Pokemon ski cap.
Evan: Traditional garb. It looks like African garb, or something.
Vince: Well, it's traditional to someone.
Evan: It's got pockets. It's not traditional if it has pockets. I mean, did they have pockets back then?
- Later, after HABIT takes Evan, this is how he describes the ritual:
HABIT: Did he really stand there, like this? For an hour? Like the Statue of Liberty playing football?
- HABIT expressing disappointment over the fact that Vinnie isn't running away and shitting his pants in terror at the sight of him.
HABIT: You're not running. You're not screaming. You're not even trying to stick me with that little pig-sticker you got there. Why?
(Sound of Vin snapping knife blade open.)
HABIT: Oh, don't take it out now, there's no point.
