I think I should start meta-punning on all my posts.

You're confusing adjective with...
heck, I don't even know how you managed to read the sign-up for southperry.

You're confusing serious with sarcasm, the only method I can use to confront Randumb_Overlord.

Also. Adjective, used to describe things. Acronym, used to abbreviate a phrase.
Because such a blatant attack requires further proof;

an adjective is a word whose main syntactic role is to qualify a noun or noun phrase, giving more information about the object signified.

Acronyms and are abbreviations formed from the initial components in a phrase or name.

I don't think meta is an abbreviation of anything, and I don't think smurf is an abbreviation of anything either.

So tell me, what am I confusing with what?
