A turn of phrase meant to insult either yourself or others for their foolishness or stupidity to the point of it seeming as if there brain is leaking out of their own skull, hence brain drain
A friend that is ordinarily quite adept at chess, horribly blunders an obvious play, the only possible explanation being a severe brain drain at the time.
