There is a super morbidly obese lady I work with that we all call her "Dozer" to her face. As in bulldozer, due to the fact that she has no spacial awareness and runs over anything that isn't directly in front of her (actual) pelvis. She has such wide "hips" (like bingo wings for hips!) that no trash can is safe from her, nor are any mailboxes that hang on the wall. It's hilarious.
