“He eh” is a very legitimate exclamation, that has mustered consensus from an inordinate number of reputable academics, prominent politicians, and other highly credible profesionalls, to not only be synonymous to the word “yes”, but to also be a perfectly acceptable - without dispute, phrase to express affirmation.
Or "He's on medication"... what it really means is that he's an a**h**e, but we don't want to admit it.
I always disgustedly roll my eyes when someone tried to play down someone's destructive/abrasive behavior by saying, "He needs more training", when I know very well that the person in question is simply a no-good jerk, and so no amount of "training" or "counselling" in gonna help him... if he's evil or selfish by nature, there's nothing that others can do to "reform" him; he himself has to WANT to change his ways before any positive progress can be made.
