Brain boof

When you have a moment where you can’t remember something that’s seemingly simple.

Used to be called a "brain fart" until the Supreme Court certified the new meaning of the term "boof" per Brett Kavanaugh.

I was at a party last night and a guy I knew from college walked in. I went to greet him and I had a total brain boof when it came to remembering his name!
