"please believe me! motherfucka, i'll kill you, i didn't touch that bitch! "

Linguists have named fill-in-the-blank idioms, such as "The first rule of X club is you do not talk about X club." They call it the snowclone. But is it laziness or cultural literacy? Lazy in that you're simply mad-libbing your own context into the skeleton of an established joke. Or repeating quotes. Is it being intellectually dishonest in humor? You're pushing someone into the piranha tank and then jumping in when they discover they're Swedish fish. It's safe. You know you'll get a laugh out of a movie quote or comedian's work. However, I will say that who doesn't enjoy a well placed movie quote or a new twist on an obscure reference. Everyone does it. People like it. Is it so bad? Is the craftsmanship in your interpretation of the comment? Timing? Situation? And understanding the reference is a little wink nudge to pop culture and being culturally literate. There's an immediate bond between the people that get it. It's the basis of most of the humor on Family Guy or the Simpsons. Crazy, I know. Crazy like a fox.
