under achiever

A female whose stomach petrudes farther outward from her body than her breasts.

Look at that fat chick with tiny boobs. What an under achiever!

Over-Under Achiever

Someone who achieves the extra unecessary achievements, but does them in a half-ass fashion.

Patrick decided to be an Over-Under Achiever when he went the extra mile to do his extra credit, even though he already had a 103 percent in his english class. This project was done in a very UNorderly fashion. The rough draft write-up ended up having its title 'rough draft' erased and then replaced with 'Final Project'.
