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.
