This only refers to single console, same room style multiplayer.
Now that I've cleared that up, I can safely assume y'all are as guilty as I am. We've all been there...getting our asses handed to us on the couch during SFII Turbo bouts back in the day, no matter what defense or offense we employ is met with defeat and much laughter. So what can a playa do?
Slap the controller out of their hands. Unplug it with your feet. Punch them for real. Spill your drink in their lap. A surprise slap right in the face.
These are but a few of my own ghetto techniques, and I'm positive everyone has their own.
What form of cheap, bastardly payback do you guys employ?
