...”Two heifers with kids were blocking the produce aisle”....
With all due respect, they cannot be heifers and have children, by definition. I would refer to them as tubbies....but your main point is clear.
Point taken....the term just seems to ‘fit’ however. The other term that comes to mind is “fat, lazy you-know-whats”
It is disgusting. I cannot remember a time in the last 3 years where I haven’t gotten behind one of them in line at Walmart. In my county, they are EVERYWHERE!
