I used to describe it as bees or flying bugs under my skin.
But its the little gremlin that shoots out from behind the chair-legs
while I'm watching TV, and jabs me with a 5" long ice-pick
a few times, HARD!!.... that really gets 'my goat'.
I've tried swatting with a fly-swatter or a rolled up magazine,
but I can never seem to catch him.
