Lately, I keep hearing this term, "covered up." At first, I thought it referred to wearing proper sunscreen in this 100-degree-plus heat we've been experiencing lately.
But now, I understand it is a reference to being busy / having a full schedule. To mix metaphors a bit, the use of the word "covered" here means that a person has so many things on his plate that he can't seem to get out from under his long list of responsibilities and appointments.
Never heard this one before, but I think I like it.
