I was a new JET Programme participant located in rural Japan. The CIR variety, so I knew a good bit of Japanese and was there to teach and write about US culture, history, food, etc.
The local dialect was pretty difficult to understand however, and I was constantly asking what words meant. One day my coworker used an expression beginning with “o”, which is a common honorific prefix, and wanting to basically say “o - what?” I clearly proclaimed “onani?” in the middle of the board of education office. More than one person stifled a laugh and my coworker almost did a spit take.
It wasn’t until much later that I learned “onani” is masturbation in Japanese, based on the English term onanism, which I also didn’t know at the time. So I basically failed hard in both languages that day.
A long time ago I wrote a little web app that takes a search string and finds all the words in the dictionary that have overlap with its spelling. Sort of a portmanteau generator. It was just a fun project at the time, but I have used it on countless occasions to brainstorm unique names for projects, websites, etc.
You can try it from the link below. Just type any word or name and it will populate the results.
