Aussie slang for glaring at people (staring at someone in a nasty fashion). Essentially the Aussie version of "stink eye".

Can also be made into a verb: "to grease off" - the act of giving someone a mean stare.
Geez Sam, Mick was giving you a decent greasy just now. What did you do to piss him off?

That dickhead just cut me off in traffic. What could I do? I wasn't gonna ram into him and smash up my own car, so I just gave him a good greasy as I drove past him.

What's with that bitch? She keeps greasing me off.
