Apropo - אַפְּרוֹפּוֹ
Literal translation: By the way, now that I think of it, Israeli Bugles
Like many Hebrew words, apropo has two completely different meanings. It is also the name of the Israeli version of Bugles (and it is an Israeli favorite), but can also be used in a sentence when something reminds you of something else.
Example: Apropo the high taxes in Israel, did I tell you I got a raise last week?
