Overlord is a unit (creature) in the game of Starcraft! Sometimes people call overlords ovies. It floats above everything else, and you cannot create other units if you dont have overlords.
Overlords can see invisible units and can also carry units from one place to another.
Sometimes people who are obsessed with Starcraft call their parents overlords. They are the higher than you, maybe thats why!
I can't create any lings coz I need to make more Overlords!
Dude that guy has mass Dark Templars in my base. Send your ovies fast.
Damnit my overlords grounded me again! I cannot play starcraft this weekend.
