Meaning: Bad, Terrible, Disgusting, In trouble, Mess up, Not good
Kanji: 不味い, 拙い
Antonym: うまい, 美味い, 上手い
Mazui is used for the taste of food and also for bad situations. The kanji for 不味い is “不(Not)” and “味い（Tasty）” means. Since “不味い” is not commonly used, it is written as “まずい” in hiragana. Mazui for taste is “bad” instead of “not good,” so it is a strong expression. “not good” is used with Oishikunai(美味しくない).
It’s rude to say mazui to the person who served the food, so be careful. Instead, it’s better to say, “I don’t like it,” or “I’m full.”
Kokono ramenya wa mazui
The ramen shop here is bad.
Kare wa ryourini shio、satouwo iresugite sugoku mazukatta desu
He put in too much salt and sugar, so it was disgusting.
About bad situation
Mazui is also used when the situation is not good. For example, when you lose something, you use mazui like oh my god. Mazui, used at this time has the same meaning as Yabai(やばい).
Saifu niwa takusanno okanega haitte itanoni nakushitesimatta。korewa mazui jyoukyou desu。
I had a lot of money in my wallet, but I lost it. This is a bad situation.
Aa、korewa mazui kotoni naruzo!
Oh my god, this is going to be a big problem！
When it means “inferior in ability” or “poor,” it is written as 拙い. Reading 拙い as “mazui” is a slang expression. Note that the formal reading is ‘tsutanai.’
“拙い” and “下手” have the same meaning, but “拙い” is more formal. “拙い” is often used to express an apology for one’s poor performance.
