This is an example sentence, not a mnemonic, but I thought of this thread when I read it and I didn’t want to start a brand new thread.
自分のウンコを食べてみて、それがすっごい苦かったんだけど、どうして苦いのかって先生に尋ねてみたら、「胆汁酸がいっぱい含まれてるから苦いんだよ」って教えてくれたよ。
I told my teacher I ate my own poop and that it was very bitter so I asked him why that was. He told me our poop contains a lot of bile acid and that’s why it’s very bitter.
Just… okay.
