👉 Alumni "fumes" refer to the lingering, often unpleasant odors that can emanate from an old college or university building after long periods of disuse. These smells are typically a mix of mold, mildew, and decaying organic matter, which can accumulate in the walls, floors, and ceilings over decades of neglect. The term "fumes" is used metaphorically to convey the pervasive and sometimes overwhelming nature of these odors, which can be particularly noticeable in large, enclosed spaces like lecture halls or dormitories. While some may dismiss them as mere inconvenience, these fumes can also signal deeper issues with building maintenance and environmental health, making them a topic of concern for current and prospective students alike.
