from what I have been told; you bust into your own house with a ski mask or a stocking brandishing a knife, gun, club or any blunt object and throw your wife, girfirend or female friends onto bed, floor, or furniture. Rip their clothing off and have sex with them. Never revealing your identity until after the action is finished.
To friend: My wife called the cops after I pulled "the robber" on her.
A gullible, and usually foreign player in GTA: SA-MP who will repeatedly ask for things and punch you, you can usually spot one if they have a name similar to "mark_jhon", or if they have terrible grammar.
