brain fact 

A thought that you believe to be true. The "facts" are completely fabricated and are supported by zero empirical evidence whatsoever. The only qualifier is that you believe the fact to be true.

Kara: "that's not a fact."
Jordon: "yes it is."
Kara: "supported by what evidence?"
Jordon: "My observations. Brain fact!"

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.
