fuzzy tire 

A man with a hairy belly who also suffers from Dunlap disease, which is when the large belly girth spills out over the belt. Theoretically, this can also happen to a woman, but because women are less likely to have hairy bellies, it most predominantly affects men. Usually when a female has this condition, it is more evenly spread around the waist, causing a roll of fat all around the top of the pants that is commonly referred to as a "muffin top".

"I wish the neighbor dude would wear a t-shirt when he mows the lawn. No one wants to see that fuzzy tire."
