Japanese equivalent of a brain fart


Is there a Japanese equivalent term(s) to describe a brain
fart/absentmindedness? I noticed the term karahenji in Jisho.




**ど忘{わす}れ** is a word that, like "brain fart," means roughly that you are
unable to recall something in the moment, but you would normally be able to
recall it easily.

It comes from **忘{わす}れる** (to forget) and [**ど** , a prefix that can be used
for emphasis or to add a derogatory tone to
something](https://japanese.stackexchange.com/q/2267/78).

As noted by kimi Tanaka in a comment, it's possible that there is a difference
in register between the two terms across languages, since "fart" is not a
polite word, but in meaning they are very close to each other.
