Germ
noun
A "ばい" bacteria is a germ. In case you're wondering, the ばい is referring to the kanji 黴, but people don't usually write that part.
The reading is the same as the one you learned with the kanji.
ホームレスだからって、俺がまるでばい菌のように人にジロジロ見られるのは、とても腹立たしい。
Even though I’m homeless, it’s really irritating when people stare at me like I’m some kind of germ.
