when u get a girl drunk/high/or slip a pill in her drink then when u fuck her, you fuck her doggystyle but with her head close to a hard surface so u fuck her and she hits her head, the goal is brain damage so u can say i fucked a girl so hard i gave her brain damage
I pulled the old killer dog on Susie last night now she has to wear a helmet.
