"So when your kids/grandkids run into the room and yell "Hi, you motherf***er!" that would be just another 'natural - everyday' term of affection then . ."
Or how about at a wedding reception? Would it be okay for someone to step up to the mic and say "This is the best f*cking wedding I've ever been to. And the happy couple? I wish you motherf*ckers a lifetime of f*cking happiness. You f*cking ROCK!"
Only a low-rent maggot would think that was okay. (Not that there is any shortage of low-rent maggots).
There is a concept called "wrong time, wrong place."
Scuse the double post. But it does bear repeating. :-)
