Waxy has coined a term:
supercuts. His definition: "Some obsessive-compulsive superfan collects every phrase/action/cliche from an episode (or entire series) of their favorite show/film/game into a single massive video montage" -- so like the
Lost What? thing I linked to yesterday.
Buzzfeed and company haven't gotten it yet, but you'll see it in 5... 4...
UPDATE:
There we go.
On Lost, they constantly have one character say something mildly cryptic, and then the other character hesistates for a moment then says "What?", and then the first character explains, usually referencing some previous incident/conversation involving the What?-saying character.
E.g.,
John: You're just like every other character on this show.
Kate: ... What?
John: You have daddy issues.
