Yeah I believe there's this weird story about how like... Onani/onanism entered the vocabulary through the Old Testament character and then the notoriously private Japanese adopted the foreign word "onani" to refer to masturb8tion and so it just sticks in my head a bit more and comes out when I feel the need to slightly self-censor in consideration of being on the work net (it's not an English speaking IT team but, you know how it goes, don't be the shortest hanging fruit).
