Moosehead Flu

A colloquial term originating from Canadian high schools, “Moosehead flu” refers to the phenomenon where students, particularly females, gain weight over the course of their high school years. This is attributed to the early consumption of Moosehead, a cheap beer popular among Canadian youths, combined with a lack of physical activity. The term underscores a noticeable change in physical appearance from freshman to senior year, often discussed among male students.

“Look at the senior girls, they’ve really caught the Moosehead flu since freshman year.”
