(man- sKAirz)-noun-At time of the morning in which a post adolescent male between the ages of 18-25, or generally of college age, experiences a glance in his mirror by which he is frightened due to his physical appearance becoming more reminiscent of his father, a generally wearing image of a middle-aged man, or actor Vince Vaughn post-Swingers. This scare either stems from a reality or misperception in which the male notices either his stomach is expanding, his hairline receding, his eyes especially sunken from a night of sleep, his facial hair half-shaven, and his muscle gone.

A casual invitation / threat used by an individual that is not afraid of fucking someone up.
