Over-Achieving Cherry 

Commonly known as: Oac (Pronounced: Oak)
Someone in the military who has yet to see combat and tries too hard to make himself look good in front of superiors, making others look bad.

Typical signs and symptoms of an OAC include, but are not limited to:
- Saying words like, "Hooah", "Squared-Away", "High-speed", "Consolidate", "Water source", "Headgear", "Too easy".
- Being the first to volunteer.
- Having cadences/The Army Song on his iPod.
- Sucking up to leadership.
- Quoting FM's and/or AR's.

*Looking through iPod*
Soldier1: "Why the fuck do you have Army running cadences on your iPod?!"
Over-Achieving Cherry: "'Cause I run to them!"
Soldier2: "Fuckin' OAC!!!"

Over-Achieving Cherry: "I just love jump week, guys.. Jumping is so fun."
Paratrooper1: "WTF? Fuckin' OAC, there's no one here to impress."

Overachieving Underachiever

One who should be in a higher position/class, but chooses not to be for the sake of easier work, social status/life, lower expectations, or just so they can feel dominant compared to their dumbed down fellow students/workers.

Michelle's such an overachieving underachiever, she should be in academic algebra, but chose applied algebra for easier work, and is now making the entire applied algebra class look stupid.

Diego chose to stay at the crappy Seneca college just because most of his friends are going to it, even though he was accepted by Harvard University.

overachieving oriental 

a term used originally by Frau (westergard), and now by many Latin 2&3 students to describe the nerdy orientals, who do pretty much nothing but study, do homework, and study again, as opposed to the white nerds or the stoner and hip-hop asians.

James Ma is as much of an overachieving oriental as u'll ever meet, man.

if it wasnt for the overachieving orientals, our whole class would fail the regents.
