(N.)(that-guy)The guy who drives at night with those blue lights on his car AND his high beams on, but ONLY uses them when it's a perfectly clear night, and he shines them right into your bedroom just to wake you up before work. He does this multiple times a night just to make sure you don't go back to sleep.
He also drives behind people to make sure they can't see SHIT.
