.... posters here choose to use instead of "sexual intercourse" or "derriere".  Some of the people I trust & respect completely use those words once in awhile. I use them myself sometimes..... maybe more than I should, but I've never claimed to be a saint.  

But then, I also I scratch my head over why movies that show one of the most beautiful things in creation, the nude human body, get R ratings while some that show bodies getting blown apart get a PG-13.  WTF??  Oh, sorry, I meant, WTSI??  ;

It has a tendency to get their attention. I use it with friends, but never in a professional setting unless people are being dumbasses and I need to make a point.
