OAC 

Over Achieving Cherry- A undeployed, or one that has not been in combat. They are dick suckers that look to impress the higher ranks by going over and beyond during any and everything they do. Also they tend on being motivated nerds.

Pvt Patton and Pvt Bovee used to follow the lifestyles of being shammer's, but decided that sucking dick would be a fun way of earning the rank of Spc fast. After getting pinned both of these nerds starting to act motivated and gay by trying to be Army "leaders". The smell of both maple logs and gay was prominent among them both. "is that home depot I'm smelling?" said Pfc Avocado. "no dude, that's just those fucking Oacs over there."

Oachkatzlschwoaf 

An Austrian slang word for the tail of a squirrel. Often used to proof if someone was austrian because germans couldn't pronounce it.

Oachkatzlschwoaf 

Derived from the proper german "Eichkätzchenschweif" which means oak-cat's (squirrel's) tail, Oachkatzlschwoaf is a word used to find out if one can truly pronounce Austrian words right.

"You think you're a real Austrian? Well then say Oachlkaskoachachselschoaß for me!"
"You mean Oachkatzlschwoaf, right?"

On A Completely Unrelated Note
A stronger version of BTW, used to signal that next statement is absolutely unrelated to the topic that has been under discussion up to this point.

(IRC users talking about arbitrary weird stuff, e.g. fishing in Norway, suddenly <A> recalls seeing something funny and not anyhow connected to it)
...
<A> OACUN, have you seen the last episode of <sitcom>?
<B> No, what did happen?
...
(IRC users talking about <sitcom> from now on, or maybe not, if it was not interesting enough)

OACD 

"Original Animated Comic Dub", pronounced either "Oh - A - Cee - Dee" or "whack'd".

Type of motion comic video format where comics (or manga) are slightly animated and dubbed over with voice acting.

The difference to regular motion comics is that this format takes less effort to produce and is referring to original content often made by independent creators. The comics in an OACD remain fairly unaltered and are true to the original artists work. Its an effort to bring comics closer to people who are too lazy to read, and a way to push unknown artists with potentially great ideas into the spotlight.

OACDs are roughly placed in the middle between comic and animation:
*Comic (static) < Comic Dub / Storyboard (no panels) < OACD / Motion Comic / Animatic (no panels) < Animation*

Have you seen the new OACD by artist?!
- Yeah, the animation and voice acting was great!
