A moon bug is a crazy person. It came from the term lunatic, which our family twisted to lunar tic, to lunar bug, to moon bug.
I can't believe you did that. You're a moon bug!

A moon bug is a one of a kind creature that possesses the purity, beauty, and gentleness of the moon when it is hanging outside of your window at night and glowing with the softness of the brush of an angels wing. A moon bug is a rare creature like a fairy, whose magic upon touching you, never leaves. He has the ability to take you to another world where nobody else can reach, and all there is in an infinite amount of warmth, love, and safety to last a lifetime. A moon bug, to put it simply, is the most beautiful person in this world.
Late the other night as I shifted restless in my bed, my moon bug wrapped his voice around me and lulled me to sleep.
