How do I burp!??

I know it's a stupid question but how do I do it D: I can't burp.... =[

How do I shot web?

Also, http://www.wikihow.com/Burp ? xD

When I'm having trouble burping, what I do is: Sit in a chair, make a fist in with one hand and wrap the other hand around it, place your balled up hands right above your belly button but below your rib cage. The next step is the most important, lean forward and apply pressure with your fist in a upward motion towards your chest (It's kind of like doing the Heimlich Maneuver to yourself). It should force the gas out of your stomach.

If I am gassy, this always works for me.
