tighten up the graphics

1) To work at an introductory-level tech position.
2) To attempt a feat without knowledge of how it can be done.

Phrase originates from a Westwood College commercial, in which two young videogame designers, dressed in 70s attire, report to their boss that they are "almost done with level 3, and need to tighten up the graphics a little bit."

1) "Once I move back to Arlington I'm gonna tighten up the graphics for Adobe Systems."

2) "I'm almost done with my quadratics homework, I just need to tighten up the graphics a little bit."
