Refers to a male's bedroom or a room inhabited by males. Testosterone, sweat, farts, and cum have given the room that dank scent reminiscent of the cage your stinking male mouse lives in.
Last night Jim was hanging with his boys playing Smash Bros til 4am then they put on some porn and had a circlejerk. Now it smells like boy mouse in here.
