Me Harborwolf. You Jane?
Either form of what? GDs or GD’s? They are *equally *acceptable, in that both are wrong, but I suspect that’s not what you meant.
The original word you are attempting to shorten to an acronym is Great Debates. Accepted usage for creating acronyms is to use the first letter of each word in a capitalized noun phrase. Mundane Pointless Stuff I Must Share becomes MPSIMS (an unpronounceable delight). Great Debates becomes… GD.
GD’s means “that which belongs to GD” assuming that you are using the apostrophe in the standard literate fashion. The secondary possible use would be using the apostrophe to indicate elision of the “ebate” portion of “Great Debates.” Feel free to claim that as your intent – it’s at least technically correct, but any competent editor will fix it for you.
I know your Internet persona is based on seeming highly educated, but please stick to your balloon animal schtick and leave English to those who use it correctly.
When you use big words, you must do so without pretense! You must demonstrate that you not only understanding the meaning of the word, but also its apppropriate use.
You choose words of little significance to the accomplished, bombastic circumlocutor. The words are obvious, and placed as they are, belying of a pedestrian intellect, at least as far as sarcasm is concerned.
Work harder, and you’ll get there. I’ll put my money on it.
Alright, I misspelled “appropriate.“
Sue me.
My misunderstanding. I thought you were referring to my use of the apostrophe in Aeschenise’s, not in GD’s. So typical. I picked out the non-error, while you were harping on a still more trivial matter. I love you guys!
Kinda hard to miss it since he quoted exactly what he was referring to in his post.
GD’s 
Really? I keep getting Marvin.
“Here I am, brain the size of a planet…”
Nah. With this whole “ultimate deconstruction” thing, he’s more Marvin the Martian.
“Where’s the kaboom? There was supposed to be a board shattering kaboom.”
In other words, you got nothin’.
Not exactly, but in the ballpark.
Would you care for a banana?
Silly girl. You can’t play baseball with a banana. You’ll slip on the way to first base.
I was “harping” on your often-repeated improper usage. I ignored the probable typo. Why is the repeated error more trivial?
And as **Harborworlf **already asked, how could you possibly miss what I referring to, as the only 4 characters of your craptacular post that I quoted were exactly the ones in question?
But you might hit a home run if you’d ditch the “Jane” schtick and address me as Josephine.*
*Might not be work-safe despite its historical significance.
He’s so smart he saw right through your ploy. You were out thought at a canter.
My that is an apeeling costume.
Or if you prefer…
In that outfit, you wouldn’t slip on the way to first base, but you’re bound to slip on the way to home plate.
So, Harborwolf, think you’re got enough on the ball to make swing with one high and inside? 
:: Grooving to the Fabulous Thunderbirds’ “Tuff Enough” ::
Are you kidding? I’ve got so much on the ball that I had to get a second to share the load.
Canter. You had to look the word up, didn’t you.
Not that that’s a bad thing. It’s just that I know you had to look the word up.
I’d be more inclined to call it piaffe.
Good one!
