A nickname for a Gonorrhea infection.

This infection is now the most common of all bacterial STDs. In both men and women, a gonorrhea infection may cause an abnormal genital discharge and burning with urination.

If you have the clap, see a doctor and get some antibiotics. And take a shower, because you're dirty.

Just after the original GeForce was released, a pastime of many owners of the Creative Labs model (the Creative Labs Annihilator Pro) liked to troll hardware newsgroups declaring, "I've got the CLAP" in order to piss off those who weren't able to afford the heafty damage.

I expect the same thing will start to happen when the GeForce 3 is released, but without the hilarious doublé entendre.

So, if a complete stranger comes up to you and shouts, "I've got the CLAP", remember to examine the context of the situation before running away.
