mandemic
1. referring to a general state of machismo affecting persons over a vast geographical area.

2. a highly contagious state of brodaciousness, or brovado, raising levels of brogesterone to dangerous levels.
What began as a modest brodown soon escalated into a full-fledged mandemic as hordes of the broletariat, as well as the brogeousie, converged on the streets, almost as if the brozone layer itself were replete with brogesterone and raining it down upon bros en masse.
