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 "Holy Shit!" 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.
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.
No examples, please. We don't need to document every single instance of someone saying "Holy shit."
