Eshkoshka is a very ancient Bootcampian word used by warriors whenever in the midst of intense combat or competition. If any man struck a blow, made a significant play, or made any power move for that matter they would yell ESHKOSHKA!!!! Meaning FABULOUS....
Why are you being such an esheon at this? Jeez, you're so being an esheon right now! A chicken pecking bird seed off of a keyboard would be more useful than you, you esheon.
