Accismus
Accismus is a feigned refusal of something earnestly desired.
The 1823 Encyclopædia Britannica writes that accismus may sometimes be considered as a virtue or sometimes a vice.
The Latin term comes from the Greek word is "ἀκκισμός", which, according to Britannica, was "supposed to be formed from Acco, the name of a foolish old woman, famous in antiquity for an affectation of this kind.".
More particularly, in rhetorics, accismus is a figure of speech, a figure of refutation, and a type of irony.
