Ping

I try to follow all the new things that appear on the web. I know how to embed video's, I'm a big fan of RSS, but I haven't got a clue what a ping is.

Thing is, these pings seem to take over my blog. Over 20 pings every day, from porn sites without exception, on my Dutch blog. Thing is, the blog is getting incredibly slow. Is there a relation between these two? Help me dear friends...
