We've all seen computers get hung up for a bit when we asked them to do a bit too much. This is often referred to as "lag".
The human brain is capable of having a very similar reaction in a variety of situations. Have you ever just completely forgotten what you were saying in the middle of a sentence? Brain lag.

That thing where someone asks you a question and you say "huh?" but then you interrupt them with your answer when they're halfway through repeating themselves cause your brain was just processing the question

F**king hate when my brain starts thermal throttling!
Looking for a word thats on the tip of your tongue but you just can't figure it out.
Me: "What's that thing...the uh..."
Me: "The thing...thingy...uh...the name of that-"
Friend: "Binder. You forgot the word binder?!"
Me: "... I have no excuse."
Brain fart. When you're answering a question and you just lose yourself and stop talking cause you basically just forgot what you were saying while you were saying it.

When you stay awake for too long and you just kind of stare of into the distance for a few minutes, which you can't remember.
