I agreed you can call yourself whatever you want. But by standers watching or witnessing these encounters will define you as a streetfighter. Thats the guy that whipped the crap out of this guy at such and such place/bar, he's a hell of a streetfighter. Or he fought this guy ..., and took a hell of a beaten he is a tough a$$ streetfighter.
If you indulges or entrapped in these type fights you are titled by association with these idoits and violent guys.
Such is life, you don't whip the crap out a guy even with Aikido (One of the most gentle arts

) and not be labled a streetfighter.
I've never heard any one say on the street, My what great control and techinque that up right citizen performed on that ruffin, he broke his arm in two places. What a gentlmen and knight of a guy. Whats heard is damn did you see the way that guy broke that fools arm. Man I'd hate to mess with him in a dark alley, hell of a streetfighter. Theres no bowing on the streets.
As for the 1-5 fights r more label, some people have never pass a blow or tasted their own blood in a fight. These people I'd say they don't have any streetfighting experince. Its like changing a diaper once you've done it you might get crap on your hands, you've been there done that. Just like there are some cops that go their career and never fired their gun on duty or pointed it at a suspect. They are still policemans, probably pretty well trained. These titles are just preceptions not self earned titles of pride & honor.
