You're actually pretty far along in figuring it out. When anon said "sense" he meant it as shorthand for everything you just described. Body language, smell, looks, tone, etc. assuming he's not retarded that is.
Keep on working on it. Try to be candid with people without being off-putting. Ignore the sperg rage when normies say something like "sense" or "vibe" and just understand they're too stupid or lazy to describe the phenomena accurately. Bathe, cut hair, brush teeth, choose a fashion that suits you that isn't too whacky or dated. Keep trying and doing experiments while changing little things about yourself. You'll figure it out.
The real mindfuck is going to be long from now. After you've successfully socially tuned yourself to get whatever you're aiming for. Girlfriend in the bed, well liked, large social circle and successful in your business. Probably realize that you had a strong disdain for most people all along and would rather do your own hobbies alone anyway. But I'll try not to ruin it for you
