I agree with Laurach- calling a kid a little bugger either means they're squirmy and a tad annoying (won't sit still) but cute, they're imitating a parent or older sib in an adorable way ( "Just look at the little Bugger!" _____said proudly), or are just plain adorable- though I haven't really even heard it used lately.
Bloody isn't even a swear word over here- at least not really. I don't think I've ever really heard it spoken in a conversation- just in a movie or two.
I don't like the F word at all- but you hear it a lot in school- maybe around 8 times a day -(and my friends don't say it- so that's from overheard conversations, like at lunch when people talk too loud to be ignored.) so I've sorta become desensitized- it pretty much has no shock value anymore. I still won't use it though, and don't much like reading it- if I actually realize it's that word and not just a swear word in general- I've read it so much my mind really doesn't notice it- unless it's repeated a lot.
As to the thong/sandals- they're called flipflops here and the thong is what you call the plastic thing that goes between two of your toes- though I believe calling it that over here originated after the actual thong- we even have book thongs now (Bookmarks) named after it
Sh-- really has little impact. It's still a bad word so I don't use it, but people use it like it is a generic mild bad word. Unless someone's suprised, shocked, or in trouble and says oh s--- it's not used too much. It even seems to be phasing out a little here- people tend to use oh F--- instead. It's still pretty common in writing though- in stories I find on the internet- and it passes just fine though editors and moniters for kids to teens stuff.
