How do you commit 'click fraud'?

[Brilliant]

I'm guessing by having some loser spend his time clicking the ad so that you get paid more.

[Major Matt Mason]

If you are the owner of a web site (or publisher) that features banner and text advertising, you personally are not allowed to click on those banners or text ads. Also, you are not allowed to entice site visitors to click on the advertising. Both of these instances would be considered click fraud because, in a situation where you are being paid per click, these clicks would only be made to receive payment and not with the intent to actually purchase a product (or whatever action is required by clicking on that ad). Now, this could be a tough thing to prove since clicks aren't created equally - not everyone that clicks on advertising is going to purchase something. Usually, though, there is probably a sudden surge in clicks that is not joined by a surge in traffic which makes it easier to spot the fraud.

There are other, more nefarious forms of click fraud, such as someone from a rival site intentionally clicking on the advertising at your site to try to cause you problems with your advertising networks. Or, if you are an advertiser, a rival could intentionally click on your ads to drive up the cost of your advertising bill.

Perhaps a javascript to automatically credit the click.

The are popups as well as popunders.

And then there are the popups that launch popups. Some such sites buy expired domain names (or buy soundalikes), direct you to a "search engine" they load onto that page and then do all sorts of nasty things to your computer (that was how I got gator's spyware without ever clicking anything).
