意味

Makes no sense — an internet-born abbreviation of 意味不明, used to dismiss something as incomprehensible.

イミフ is the condensed, snappier version of 意味不明 (imi fumei). It is used almost exclusively in casual text-based communication — LINE messages, Twitter/X posts, and online comments. The abbreviation makes it quicker to type and gives it a more dismissive, flippant tone than the full form. It is part of a broader trend of abbreviating four-character compounds in online Japanese.

例文

1. あいつの言ってること完全にイミフなんだけど。

3. イミフなLINE送ってきたけど、酔ってたのかな。
