Dean: What are you looking for?
Sam: I dunno, a little... panic, maybe?
Dean: Well, I guess I'm a little numb to the earth-shattering revelations at this point.
Divide the number of times you said or thought, "Holy Shit!"note by the number of scenes. This is the Holy Shit Quotient (or HSQ) for a given episode. The term originated somewhere among the Buffy the Vampire Slayer (Buffistas.org, most likely) and Television Without Pity communities, where it is occasionally still possible to get a nice little Flame War going over whether or not "HSQ" is pronounced "aitch-skew."
It is sometimes shortened to form the verb "skew." As in: "The episode skewed me to the chair."
Wham Episodes tend to have a high HSQ, as do Professional Wrestling matches involving Spot Monkeys. This is in fact a common chant at pro wrestling events when something like that happens. Heavy Metal and Visual Kei bands try to have at least a moderate one of these per promotional video and/or concert, though it often ends up as Narm if failed. Obviously, that's a matter of opinion.
HSQ-raising moments are Shocking Moments. Anything that has Serial Escalation somehow is guaranteed to have a high HSQ. When writers try to increase the HSQ of a scene that doesn't have punch by having the characters (or camera work) pretend it does, they often wind up using Mundane Made Awesome.
