Call me old school but when anybody uses acronyms for swear words or swear words, they have zero credibility. No response on my part needed. I just walk away. Now in a bar might be different, I might puff out my chest and use the f bomb but I confess that I don't have the muscled body or the youth to back it up. Only been punched out once. Really don't like it. Putting WTF on the back of your work shirt - means that u r biting the hand that feeds u. Don't like that either
