  1. Hey Maggie! Ignacio here. I was looking for the etimology of ダサイ, its origin, and found out that you made a post of the word long time ago. Where does it come from?

    1. Hi Ignacio,

      One of the theories is from an old expression だしゃ which refer to a person from the country.
      This word has spread and became very popular when a comedian, Tamori, mock on Saitama prefecture as ダ埼玉= da saitama making a pun.

    2. @Ignacio, I remember someone explaining it on TV (it might have also been Tamori) that it comes from 「だって、埼玉だもん」. I can’t really say if that’s true or not, or if it was just his play on the word.

  2. Can it ever take the opposite meaning? I mean, this happens with slang sometimes, right – for instance saying – that’s so bad! – i.e. to mean good?
    On a recent pop video in YouTube, someone posted a comment: “衣装ダサい(褒め言葉”
    An opposite meaning would make better sense? – I thought the bit in brackets pointed to that too. Plus, the outfits were cool (well, that’s what I thought //0//…
    What do you think? When I tried to search on ‘dasai’ used positively,… I came up with nothing so, wasn’t sure…

    1. @nonoji

      A word ヤバい is yes. You can use it in a positive way and negative way.
      Unless it has (褒め言葉) or (いい意味で)etc, we take ダサい as a negative word.
      However, sometimes you combine with other positive word to create another slang.
      ダサい dorky +かわいい cute, adorable =ダサかわいい。adorkable
      ダサい+ かっこいい cool =ダサかっこいい dorky but cool

  3. Dasai. A cool word, even though..er, it’s so uncool.

    My friend Masumoto just emailed me (which is why I found your blog) about how Saitama translates as ‘Sh*t F*ck’ in Taiwanese.

    He’s in Taiwan at the moment and from Saitama. The two are related. As he describes Saitama as ‘dasai’ and ‘kusai’ to anyone who will listen.
