Sometimes a grown-ass man gets into a fight. From time to time you might win a fight. But, under no circumstances should you be bragging about a fight. In adulthood, fights should only happen if the aggressor leaves you no other option. Those years of karate lessons aren't something you should look to show off, but rather should be something you've got in your back pocket just in case. While watching somebody kick someone's ass is actually kind of cool (if the person whose ass is getting kicked deserves it), hearing someone talk about the time they punched out a guy's teeth is about as exciting as hearing a step by step account of mortgage refinancing. Of course, the best reason not to brag about fighting is that it is a great way to get you into more fights that you could potentially lose.
