beyond, did you ever play
Mad Libs when you were a kid? The labels for the blanks are the meta-terms for the words you'd actually put in the blank spaces.
Or look at geckzilla's first post on the meta thread. It reads in part: "Thinly veiled insult to intelligence. Link to Wikipedia article."
She doesn't say
what the "thinly veiled insult to intelligence" is, nor what Wikipedia article she's linking to. If there were a form to be filled out for writing a post to insult someone and then provide the person with a source of information, the phrases she uses could be the labels on the form. Likewise, BMAONE23 posted "Thread hijacked by SPAM poster." He didn't actually post spam; he just followed the form of a thread being hijacked by a spammer. (This was hilarious, as was his long drawn out narrative post; he not only metaed the messages, he illustrated them by repeating the first and making the second one literally long and drawn out. I've seen a few meta threads, but had not seen either of these things done before, and I laughed my head off at these!)
If you wanted to write a boy band song, you could follow the formula or labels that "Title of the Song" lays out. Pretend you're 19, had a great girlfriend who you cheated on which made her dump you, and now want the girlfriend back so are writing a song to let her know you're sorry, you love her, and you want her back. How would it go? Just fill in the blanks!

Does any of this help? (That question could be metaed as "Interrogative as to effectiveness of post.") I don't know that I can make this any clearer. (Meta: Expression of doubt as to abilities to illuminate the subject at hand.)
