wow I had no idea this was an actual word. you learn something new everyday. But somehow I think Ennis and Jack are using it in a different way :D

(this replaces the term "well don't screw with it just leave it alone." Which could have been used in BBM when Ennis said the tent didn't look right. Jack could have said "well don't brainfuck with it just let it be")

Thanks for enlightening me
