brain fart

When you lose a thought.

Example: You are sitting at your desk immersed in a frickin' huge coding problem when your stomach growls, so you decide to go to the kitchen for a sandwich, but you are so occupied with the problem that when you arrive at the kitchen, you forget why you went there.

Really large brain farts might leave behind brain-droppings...

brain dump = B = brain-damaged

brain fart n.

The actual result of a braino, as opposed to the mental glitch that is the braino itself. E.g., typing dir on a Unix box after a session with DOS.
