怨憎会苦
on.zou.e.ku

Literally: resentment – hate – meet – suffering

Alternately: The pain of coming face-to-face with someone you detest, or at least dislike. This is another one of the “eight sufferings” of 四苦八苦.

Notes: While I’d have thought that all of the 八苦, or at least the latter four, would have their origins in the same text, that doesn’t seem to be the case: in contrast with last week’s yojijukugo, this phrase is attributed to the Lotus Sutra (Japanese 『法華経』 = Hokekyou).

Please try to refrain from this kind of greeting, though! Source: a violent demon-fighting manga from 2015 titled 『衛府の七忍』 (Efu no shichinin)
