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.

Get the Moosehead Flumug. A flu consisting of partying for 6 days at Bonnaroo while your body is a trash can for drugs and alcohol resulting in your body’s immune system lowering from being around sweaty wooks, the sickness usually consists of coughing up phlegm, headaches and throwing up, you will probably be bed ridden for days and down Dayquil and Nyquil like a degenerate while suffering random coughing fits and the cold embrace of feeling like death
