Dasa-i (ダサい) is a quintessential Japanese slang term used to describe something or someone that is uncool, tacky, unfashionable, or simply lacking in aesthetic sense. While it often refers to clothing choices, it can also be used to describe behavior or situations that are embarrassing or pathetic.
The term is widely used across all generations in Japan. You might hear it in fashion magazines, casual conversations among friends, or even in casual office settings to describe a design that misses the mark.
Friend A: “This shirt is on sale, should I get it?”
Friend B: “Ehh, chotto dasai ne.” (Ehh, it’s a bit tacky, isn’t it?)
Using this word carries a negative connotation, so be careful when using it—especially if you are talking about someone’s personal appearance directly to their face, as it can be quite blunt.
Pro-Tip: If you want to soften the blow, you can say “sukoshi dasai” (a little uncool). Also, if you think something is ‘cool’ instead, you might use the term kakkoii, which acts as the direct antonym to dasai.
