brain afk

When a person is not paying attention, distracted, daydreaming or considered mentally unattendant, they are usually discribed as "brain afk".
afk is an abreviation for "away from keyboard", usually used by the gaming community to indicate when a person has left their computer (e.g. to get a drink, go to the toilet etc.) and therefore unable to act in-game.
"brain afk" is meant to describe a persons mentality to (metaphorically) have left their brains temporarily, being the reason for the person to not pay attention or realize what is happening in their surroundings.

Teacher: Can someone please give me the answer to the question?

Student: What was the question? I was brain afk when the question was asked...
