They are very skilled at sizing up people, and poking weaknesses, if they choose, and just general smack talk, haha (which I respect).
I'm a laid back guy, but have noticed some ENTJs tend to take that as weakness or something. The ones I know have no problem verbally embarrassing someone in public. A few have tried that with me, and well, homie don't play that, haha (One ENTJ told me "you are like, REALLY mean to me" But the reality was that I only gave what I got). I'm not sure if all ENTPs are developed enough for straight up cutting verbal duals, but they certainly have the potential.
Some of the ENTPs I know (there's not many) that are more developed can easily counter an ENTJ jab with a right cross KO. THEN they seem to give respect, and that's when we get along. I think that's because ENTPs see more angles. It's like this weird, Alpha vs. Alpha, then we hug.
