How do you punch someone over the internet?

[Henry Zhou]

On Facebook, there are these really annoying swagfags that comment the dumbest things like: when they see a mortal kombat photoshopped battle they type: "FAKE". Someone please tell me how yo punch someone over the internet.

Sorry to say you can't punch someone over the Internet.

You can't do it physically.... obviously.
