I once told a young 20 something girl, who always wore the tightest jeans I've ever seen, that she had a smoking hot body and that I wanted to rub oil all over every part of it.
Sure enough, she got 'offended' by my innocent, honest complement. I learned something that day, which I still abide by. If you're ever going to complement how smoking hot a woman is, don't do it while you have an erection. Words to live by man. Words to live by.
