A personal valet, a butler/secretary of sorts. "Do I need to get a birthday present for anyone? Seems someone's birthday is this month." "Yes, I already took care of that for you, your mother." "Great, what did I get her?...so when I talk to her I know what it was."
A body man or body woman is, in U.S. political jargon, a civilian personal assistant and sometimes valet to a politician or political candidate.
Also called the “bag woman” as she carries around a large satchel containing anything the Congresswoman might need throughout the day.
I got my knowledge of ‘bag’ or ‘body’ people from watching Gary on Veep. So funny.
