Brainfart 

n. A massive, horrible release of stupid that is often offensive to the senses and may create a social faux pa in some settings. Brainfarts often result in an intense feeling of embarrassment and shame compounded by an inability to explain what the hell just happened.

I was supposed to call Roy Blount, Jr. for an interview at 10 a.m. PST, but I had a brainfart, forgot how to tell time, and managed to call him at 6:00 a.m. PST. I feel like an idiot.

Everyone at the meeting waited for Jim's response as he finally snapped out of his odd gaze into an unseen abyss. "Sorry", he said, "I just had a brainfart, what were we talking about?".

brainfart post 

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??!!
