I can’t remember the name of the guy who tried to force me to buy an expensive rosary.
A number of pearls, put together on a string. This refers to a rosary or prayer beads. You'll see these a lot in Japan, for sale or with monks wearing them.
The reading for this word is different from both of the kanji readings you learned. This word sounds a lot like Jews (じゅず), so we'll have to go with that. Just imagine a Jewish rosary or prayer beads, with a Jewish person using it.
