All I know is the seven words you can't say on t.v...fuck...shit...piss...damn...cocksucker...motherfucker....and tits!!But as far as what is accetable or appropriate one would have to use ones own self control pertaining to the situation.But intelligently speeking,rational thought would dictate that one would not need such slang as to prevert the english language in such a manor as to embarras ones self or anyone else.(also it is a bad habit to get into!)conscious thought and awareness that one might have a problem is the first step to correcting the problem.And of course if all else fails,FUCKIT!!!and just use your normal speech paterens.Although this atitude may not always be the best recourse for making friends or getting along in life.(im just saying)
