Orbitross
Someone who is too shy to make the first move and talk to you but cannot resist your charm therefore 'orbits' around you and perves at you like an albatross from far away.
The guy standing over there is being a bit of an Orbitross, maybe I should go talk to him?
That stalker's orbitrossing me! Bastard!
