"Comedic" - unnecessary and annoyingly trendy word. It could be useful if it meant "to do with comedy, but not itself funny", e.g. a serious academic paper on the nature of comedy, but in fact it is simply a synonym for "comic", that wastes a syllable and two letters.
Similarly, "empathy", which has no discernible difference in meaning from "sympathy", but sounds (to me, at any rate) colder. (I am aware of that tiresome youtube video with the patronisingly childish animated animals, so don't bother posting a link; I am unconvinced.)
"Issues", when used as a euphemism for "problems".
"Sociopath" - means the same as "psychopath", but gives the user a fake aura of cleverness (they hope).
