A guy that seduces multiple women at once, regardless of whether he’s in a relationship or not. Mash will usually talk to women from different areas, so that they will not learn of each other’s existences.
Girl 1: I just got a new boyfriend, his name is mash!
Girl 2: Oh really? Because it seems like he’s my boyfriend too
