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."
