Beast Boy Mystery

Excuse me, my friend, if you'd be so kind
It appears that I'm in somewhat of a bind
There's something that I've been trying to find
Though I've looked high and low, it remains undefined
I see something in you that may serve to remind
Please help me my friend, if you'd be so inclined

Perhaps you should bother to glance behind
There's an obvious bugbear to which you are blind
That your handheld device cannot help you find
And to which your fate you have wholly consigned
I know this may sound a bit harsh and unkind
What you seem to have lost is your rational mind
