Commingly meaning to think of something after the fact for example after a fight or in class with an answer and forgetting
by jake fool May 13, 2007
A post showing up on a social media page or group that is totally off topic, irrelevant or incoherent. It takes an average time of thirty seconds to click the link and read enough of it to realize it is a total waste of one's time. For example, on a group with 7,000 members, that one post has collectively stolen an hour of life from those people.
I just clicked on that post on the embroidery group and had to watch a brainfart post of a stupid video of a puppy puking up a sock! Did that guy really think the world of embroidery would be made better with that video??!!

V. The act of forgetting something everybody knows or should know, or forgetting something you were recently told.
She told me he had been picked up by the police for outstanding warrants. I was brainfarting when I was texting him the next day, asking what he was going to do later.

When you try to think of something and you get so close to remembering what it was but then you lose it.

A BrainFart is where you are talking and suddenly forget what you were talking about, and realise you started rambling about something else.
