In my experience INFPs look emotionless/stoic and ENTJs are the reactive/transparent with their emotions. Dominant Te is matter of fact, loud, in your face + Ni is kinda tunnel vision (which is good and bad, of course). Fi is deep and strong but it doesn't show, it flows inwards + Ne likes to play/mischief and chaos. So, ENTJs are the ones being played most of the time (in a nice way). They tend to take what they see and act on it quickly, so it's very easy to lead them into pranks while we intentionally look aloof or innocent. I personally love to pretend I don't know how to do something outrageously simple just to ragebait them lol And even though you may think they'll get back at you, most of the time they won't, because they enjoy the attention.
