if you are not calm - it's tilt.
If you think - wow, he is buffing, i'll punish him with even top pair - it's tilt.
I can so relate to these, except I punish him even with air
oh or call him down with medium strength hand.
Earlier I wasn't able to recognize tilt even during a whole session, luckily now I see big one just after one hand, and maybe medium one in 3
hands. Small ones not yet without break to think about it. When I notice big one I push sit out next bb and hope I don't get playable hand before break (cash), if I do I so hope nobody calls (this even with AA) if they do I curse loudly in my mind and try to 120% concentrate, failing of course. But I try to keep folding mentality on by repeating it in my mind.
I do think that probably there are different kind of tilts for different personalities.
One my tilts is only seen by red line going down, not sure why, but at that time I don't win much, I can't pinpoint any obvious reason, and so it takes time to notice. Not sure you can call it pure tilt though.
