Son , please excuse all the well intended advice, for a moment, and listen to an old guy who has never weighed more than 155.
If you can avoid the confrontation, by all means, do so.
There are no winners in a fight, only the bigger and the smaller loser. One loses teeth, the other gets cut knuckles.
A bazillion years ago, Chuck Norris ran a little dojo in Redondo Beach, Ca.
I was there. Studied Shotokahn Karate, for a while.
Spent several years in 5th SF group, before that, 1st, trying to get a leg up on the other guy, and teach my motor skills to others, with "not too splendid" results.
Been to jail, and worse, 'cause many people don't understand the pressure you are now feeling.
Bottom line: If you can talk, walk, or run from a fight, the smart money is on doing just that.
If none of the available options include any of the above, (1) By all means get the first lick, and (2) Since nuts, knees, and noggin all at least SOUND like they start with the same letter, pick one, kick one, and go back to "talk, walk, run"
I know, at first reading, this sounds stupid as hell, but re-read it.
Stay out of trouble, stay out of jail, and live large.
Don't start no s**t and there won't be none, Terry
