When a overweight male or woman wears an untucked oversized shirt. Occurs when the shirt hangs over the belly due to beer or in a rare occasion, cookies.

The opposite of the dun-lop effect which is when one's belly dun-lops over their belt.This can also be interpreted as being linked to the tire brand name "dunlop," as in rare occasions, the fat creates a tire-like illusion around the middle.
Look at the blouse effect on the grumpy man who eats too many cookies, sugar free of course.
