Something that you will eventually get and continue to get once you become a Marine. Getting the "big green weenie" may include such fine events as: getting fucked with duty on a particularly important weekend, getting in trouble for some small petty shit while being in garrison, getting stationed at a shithole like 29 Dumps.
The "big" represents the big bad Marine Corps picking on the little guy, the Marine. The "green" represents the true color of the Corps. The "weenie" represents getting fucked over.
LCpl Hooligan: What I got duty again?! Dude Im getting fucked in the ass by the big greenweenie!
Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
