Se me fué el avión
Used when someone loses their train of thought, forgets what they were saying, or gets distracted and stops paying attention to a conversation or task. It is the equivalent of saying someone spaced out or their mind went blank.
Sorry, se me fue el avión, what were you saying? I was driving and se me fue el avión, now I am lost. Se te fue el avión man, you are not even listening to me.
