I heard this exchange from Friends (an American TV show):
A: They do you.
B: Do me?
(Unfortunately, I don't know the episode number.)
The context is that A is B's assistant and she is trying to give B (a boss) some feedback about how B's team members think of him. I figure "They do you" here means they imitate him, such as his behavior, the words he said, the way he speaks, and etc.
Am I getting it right? Is it a common usage?
