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.”

Man Flu

A term used by women to dismiss men when they are sick. Even though there is evidence to suggest that viral infections in men may be more severe than in women.

Becky: My boyfriend doesn't want to go shopping with me because he's sick
John: That sounds reasonable
Becky: No it isn't. He's not really sick, he just has man flu and wants attention!
