ETYMOLOGY
from miso- (hatred or dislike of), + Greek γελαστός (laughable) + -ic;
apparently after agelastic (never laughing, hating laughter)
EXAMPLE
“… We have in this world men whom Rabelais would call agelasts; that is to say, non-laughers; men who are in that respect as dead bodies, which if you prick them do not bleed. The old grey boulder-stone that has finished its peregrination from the rock to the valley, is as easily to be set rolling up again as these men laughing. No collision of circumstances in our mortal career strikes a light for them. It is but one step from being agelastic to misogelastic, and the μῖσογέλως, the laughter-hating, soon learns to dignify his dislike as an objection in morality. …”
