A snowclone is a type of cliché sometimes defined as “a multi-use, customizable, instantly recognizable, time-worn, quoted or misquoted phrase or sentence that can be used in an entirely open array of different variants.”
I find them interesting. You know? Those phrases that have such a distinct identity, you can leave some blanks (to be filled in to fit what you are trying to communicate) and people still get the reference. I don’t think I have ever played Mad Libs, but I bet I would enjoy it because it is built around phrasal templating (is that a word?). Here are some I like (and yes, I actually threw all of these into this image via www.picnik.com).
Give me some for my collection.
Oops..I see one of them on there twice.
