Going off in your own little world when somebody is talking to you, or you are meant to be paying attention to something important.

Particularly in conversation, when being given a lengthy explanation of something but then realizing that you are no longer listening and have to ask them to repeat it.
James: Yo dude, were you listening to anything I just said?
Jake: Sorry man, I was just totally #jakingout could you repeat it?

Flo: My phone keeps not getting any messages through, it's so annoying.
Sarah: Oh my, I can't deal when my phone does that, they call it #jakingout
