Hmm. Interesting approach!

Two decades ago, when I was learning how to say "unidentified flying object" in Japanese, on the day that I first heard the three-word phrase, I spent the rest of the day constructing ridiculous example sentences pertaining to UFOs, things like "My UFO is dirty and needs to go through a car wash; I don't have a UFO license; that UFO is being piloted by a giraffe." (The reason for the ridiculousness is the fact that emotionally charged experiences tend to be more memorable compared to boring moments, so funny phrases make you laugh and help you remember better, essentially).

The next morning I woke up and the first words out of my mouth were MUKAKUNIN HIKOU BUTAI (未確認飛行物体). That's the Japanese vocabulary for U.F.O., and I never ever forget how to say this, as it's now firmly embedded in my mind. I like this technique for memorizing new vocabulary. It works for me!
