I don't see what parts of this post qualify as 'a fourth grader cussing without his parents around'. Is it using the idiom 'fucked up' once and paraphrasing thoughts and excuses using 'fuck' and 'crap' on two occasions? These are words people actually use and think. Sometimes you don't just make a mistake: sometimes you fuck up. Sometimes you don't just use an excuse; you use a crap excuse. I'm not sure a professional writer would put it differently, when this is the language of our times.
