If you ask me about a certain coworker, housemate or distant relative and I respond with “they take up a lot of space”. It's not a compliment, it’s a generic long-story-short response that may encompass a variety of human relations issues in addition to actual cubic feet of physical space.
This rad power couple takes up a lot of space. In my field of vision, on the train, on the elevator, on the sidewalk, in the bike lane, in the city of Seattle. Perhaps in their minds they’re traveling light because they left their 57-foot 5th-wheel trailer on their Ford F550 in a WalMart parking lot to skeet around downtown on their “bikes”.
