A brain fart is that frustrating moment when your mind goes completely blank — you forget a word, can't remember why you walked into a room, or blank on an answer you definitely know. It's humorous and self-deprecating, used to explain away embarrassing mental slip-ups.

Brain fart就是那种令人抓狂的脑子完全空白的瞬间——忘了一个词、想不起来为什么走进这个房间、或者明明知道答案却突然想不起来。这是一种幽默的自嘲，用来解释尴尬的思维断片。

Un «brain fart» es ese momento frustrante en el que tu mente se queda completamente en blanco: se te olvida una palabra, no recuerdas por qué entraste en una habitación o no te sale una respuesta que sabes perfectamente. Es un término humorístico y autoirónico que se usa para justificar despistes embarazosos.

ブレインファートとは、頭が完全に真っ白になるあのイライラする瞬間のこと。言葉が出てこない、なぜその部屋に入ったか忘れる、絶対知っているはずの答えが出てこない。ユーモラスで自虐的な表現で、恥ずかしい物忘れを軽く済ませるために使われる。

Brain fart는 머릿속이 완전히 하얘지는 그 짜증나는 순간이다 — 단어가 생각나지 않거나, 왜 이 방에 들어왔는지 기억이 안 나거나, 분명 아는 답이 떠오르지 않을 때. 유머러스하고 자기비하적인 표현으로, 부끄러운 정신적 실수를 설명할 때 쓴다.
